Bethany,
Your question cut off, but let me see if I can offer some help.
Because multiple daily trips is out of the question, you will want to weigh how much time you spend at the parks each day.
One important helper to your day, knowing you have two toddlers, is to figure out how to give them a bit of a breather, maybe even a nap, in the middle of the day. Make sure you use the
Baby Care Centers that are in the four theme parks. These great (and FREE!) resources have great rooms with comfy couches, TVs playing Disney cartoons, books, and some toys. There are even nursing rooms. They could be a place for you to get those 2 toddlers our of the sun and the excitement for an hour or two of quiet time.
If you go to my bio page and ask me a question directly, telling me your travel dates and any other relevant information (like if you want to see more of one park or another, or if you plan on watching fireworks), I can make some recommendations on which parks to go to on what days!
Have a magical vacation!
