Ronny,
Here is what I would do;
- May 23 - Magic Kingdom (all day)
- May 24 - Animal Kingdom (AM) / Hollywood Studios (PM)
- May 25 - Epcot (AM) / Water Park (afternoon) / Epcot (evening)
- May 26 - Hollywood Studios (AM) / Magic Kingdom (PM)
- May 27 - Magic Kingdom (AM) / Water Park (afternoon) / Hollywood Studios (PM)
- May 28 - Magic Kingdom (all day)
This is how I would start off. It gives you more time at the Magic Kingdom, since there is more to do there. And I have you enjoying just about every Extra Magic Hour available (both morning and evening). I do that because when I have visited in late May the crowds have been ideal, so more time is better.
Now if you want help with dining, I would love to oblige. Let me know for what meal (Breakfast/Lunch/Dinner), what dining type (table vs. quick service), any cuisines likes/dislikes, where you will be (park, resort area, etc.), and any specialty interests (characters, shows, entertaining, fine dining, etc.). From that I can make a few suggestions!
Have a magical vacation!
