Your Parking Reservation Has a Start Time and an End Time. Both Are Rules.

Enter after the start, exit before the end, and assume one entry only. The SpotHero rules that decide whether a booking works — including the two vehicle measurements that add a fee on site.

A parking reservation looks like a purchase and behaves like an appointment. You are not buying a numbered bay for the day; you are buying permission to be inside a garage between two specific times, in a vehicle under a specific size, with one entry and one exit. Most of the ways a booking goes wrong are a failure of one of those three conditions rather than anything to do with price.

Key facts

• Enter any time after the start, exit any time before the end. Outside that window you risk extra charges, a ticket, or towing.
• Most facilities do not allow in and out. Leaving to grab lunch can end the booking.
• Cancel up to the minute before it starts for a full refund. Once it has started, there is no cancellation and no refund.
• Refunds can take up to 21 days to appear.
• Oversized means taller than 65 inches or longer than 181 inches, and it costs extra, paid on site.
• Airport spots can be booked up to 364 days ahead; most other parking runs to about six weeks.

The two times on the pass are the contract

SpotHero states it plainly: “You can enter at any time after the start time listed on your Parking Pass, and you can exit at any time prior to the end time.” Arriving before the start or leaving after the end may bring additional charges, a ticket, or towing.

That reads as obvious until you consider how people actually book. The instinct is to reserve for the hours you expect to need and treat the edges as soft. They are not soft. A flight that lands forty minutes late does not extend your window, and the garage barrier has no opinion about why you are there at 11:40pm on an 11:00pm booking.

There is one documented exception, and it is narrow: event parking allows an extended exit at no extra charge, provided you leave right after the event ends. That is a concession for stadium traffic, not a general grace period.

The practical move is to book the window wider than you think you need at both ends. The rate you see covers the whole period — “the rate that you see when you enter your date and time is the rate you will pay for that entire period of time” — so an extra hour of margin is usually cheap relative to the cost of being wrong.

In and out is the assumption most people get backwards

This is the rule that catches ordinary, reasonable behaviour. Most facilities do not permit multiple entries and exits on one reservation. Park, leave the garage on foot, come back — fine. Drive out and try to drive back in — often not.

If you need to move the car mid-booking, you have to confirm it in advance. SpotHero’s guidance is to check the spot details or amenities for an explicit “in and out allowed” marker before you book. Absence of that marker means assume not.

This matters most on the bookings where it is least obvious: a full day in a city, where you might reasonably expect to shuttle between two places. That is exactly the scenario where a single-entry reservation quietly fails.

What the guarantee actually promises

Worth reading precisely, because it is narrower than the word suggests. SpotHero guarantees “you will have a spot to park at the price you paid or your money back.” It also says openly that it does not physically hold a specific space for each reservation — parking partners supply inventory information so the lot is not overbooked.

So the promise is commercial, not physical. If the arrangement fails, you are made whole in money. You are not made whole in time, and the money can take up to 21 days to come back. On an ordinary Tuesday that is an annoyance. Before a flight it is not a remedy at all, which is an argument for building in slack rather than relying on the guarantee.

Two vehicle numbers, and a category that is simply refused

Oversized is defined rather than judged: taller than 65 inches or longer than 181 inches. If your vehicle crosses either line, there is a separate oversized fee, it is charged on site rather than included in your reservation price, and it appears in the spot details and on the Parking Pass under “Things You Should Know”.

Sixty-five inches is not tall. A good number of family SUVs and crossovers sit above it, and their owners do not think of themselves as driving an oversized vehicle. Measure once and you will know for every future booking.

Separately, and absolutely: “SpotHero is intended for personal vehicles only, so we cannot accept reservations for RVs, vans, or buses.” That is not a surcharge, it is a refusal.

Changing a booking, and the one thing you cannot change

Reservations can be edited or cancelled up to the time they begin, and most active reservations can be extended, subject to availability. Cancel before the start and you get a full refund.

What you cannot do is move a reservation to a different location. There is no transfer. If you have booked the wrong garage, the only route is to cancel and rebook — which is fine before the start time and impossible after it, because once a reservation has started it cannot be cancelled or refunded.

The window for fixing a mistake therefore closes at the moment the booking opens, not at the moment you arrive.

✈️ Compare airport parking rates

Airports run on a different clock

Most parking can be booked around six weeks out. Select airport spots go to 364 days — effectively as soon as you have a flight, you can have parking. Coverage runs to more than 70 airports across North America.

The economics are genuinely different off-airport. At O’Hare, SpotHero lists parking from $5 to $47 per day, against the airport’s own Economy Lots F, G and H at $15 to $22 per day. The cheap end of that range is a long way from the terminal, which is where the detail that matters lives: shuttles “are also offered by many offsite parking lots, but are not universal.”

So the filter to apply is not price. It is shuttle, then price. A lot that saves you eleven dollars a day and leaves you without a ride to the terminal has not saved you anything.

Monthly parking is billed like a subscription

If you are parking regularly rather than occasionally, the rules change again. Standard billing dates are the 1st and the 15th of each month. Some facilities allow a flexible start, billed five days before the following month begins.

Two things to know before committing. Monthly parking is not prorated except in extenuating circumstances, so starting mid-cycle does not mean paying for half a cycle. And access cards or transponders are charged separately, at the garage office, after the purchase — a cost that does not appear in the price you booked at.

The short version

Book wider than you need at both ends. Assume you get one entry and one exit unless the listing says otherwise. Measure your car against 65 inches and 181 inches once. Fix mistakes before the start time, because afterwards there is no refund and no transfer. And for airports, sort by shuttle before you sort by price.
