We have 7 park tickets! Also keep in mind we have park hoppers
At this point you need to plan your fast passes, as you're well within your 60 days. Also since May is around the corner look to getting some dinner reservations. You may have some slim pickings because people select their reservations 180 days out.
You state you'll be there for 7 days and you have a 7 day ticket. What time do arrive/depart? My trips are such that they're really not good days to visit the park, i.e., arriving late that its not worth a park visit. Conversely our departure flight is such that we leave the resort around 7:00am. If you have similar arrival/departure schedules, then cut back on the tickets. Why pay for something you won't need.
Dining: I recommend a few places,
Dinner show: Hoop Dee Doo review
MK, Libterty Tree Tavern
Epcot -there's so many good places to eat I cannot recommend any one place. They're all good
HS - Mama Mias
If you are able to do a full 7 days then here's what I say:
I'd look for at least
2 days for Magic Kingdom,
2 days for Epcot.
1 day for Animal Kingdom.
1 day for a water park
1/2 day at the resort/downtime
1/2 day at hollywood studios (lots of construction so it may be limiting).
If you're a fan of Harry Potter then maybe consider a trip to Universal.
If you arrival/departures are such, then cut back on Epcot by a day and drop the water park
