Hello,
Decide:
1. Which park you are going to each day
2. Where lunch and where dinner ( make a chart )
3. Call WDW Dining and make all of the table service reservations ASAP, they fill up very, very very fast!
Make dining your first priority.
My family and I have gone to WDW over 8 times. Our favorite dinner table service restaurants are:
Tonys Town Square for dinner, Be Our Guest for dinner - Both at the Magic Kingdom
Via Napoli and Teppan Edo at Epcot
50s Prime time Cafe at the Holl. Studios
On the Animal Kingdom Day, we go to the Polynesian Resort after and have dinner at Ohana, my families favorite restaurant at WDW. Then we watch the Electrical water pageant and the fireworks from the Poly's beach.
There are also many character meals that get raves, such as the Garden Grill at Epcot or Chef Mickey's, and many others.
I know it sounds crazy, but grab the reservations quickly before you get boxed out, you can always drop them later.
