Hi, Sharel!
If you have Base tickets, you will have to enjoy just one park per day. You can take a mid-day break then return later that day, but it must be back to the same park.
In my previous answer, I gave you restaurant suggestions for Magic Kingdom, Epcot, and Animal Kingdom, but nothing for Hollywood Studios! If you need a dining location for the Studios, I suggest either Sci-Fi Dine-In Theater or 50's Prime Time Cafe. Both would be fun for your girls!
I hope this information has helped and not confused you even more! Just make your plans for one day at a time. It is almost like a puzzle, and once you have it complete it is so much fun to take it all in to see the magic you have planned! Just a few days until your vacation, so have fun making your last minute plans. I will be here to help, so let me know if there is anything else I can do to make your vacation magical!
