Disneyland - One Hour Free!

Disneyland designed a program to allow park-visitors to go back into the park for an hour to have some time to shop for things they "forgot" to buy. (This is only at Disneyland in California)

Just go to the Guest Services Windows near the main entrance where you will make a deposit on your credit card for a whole day's ticket, and just be sure to return before your specific time and they will return your deposit.

Only one person in your party is allowed to do this, and they are really strict. Also, this doesn't always work if you haven't gone to the park with a regular ticket in the near past and can prove it with a receipt--sometimes they ask to see it, sometimes they don't.
