Hi Haley,
No worries! All
Walt Disney World tickets -- whether they are single-day park tickets or parkhoppers -- allow you to exit and re-enter the same theme park as many times as you on the same day. Many families are like yours and need to take a break at some point during the day for naps, a swim or a meal at a nearby resort. So you will be in good company!
You don't need a handstamp or other acknowledgment for re-entry. If you have been at
Magic Kingdom in the morning, you will simply scan your ticket cards or
MagicBands to re-enter Magic Kingdom later in the day.
Since you live in Florida, make sure you check out the
special offers for Florida residents. There are some really great deals for those of us who live here.
Thanks for checking in with the Disney Parks Moms Panel. I hope that eases your concern about the tickets, but don't hesitate to come back and ask us any other questions you have about planning your Walt Disney World vacation. Enjoy!
Wilma
