For a week stay, I'd suggest getting the refillable mugs. You'll get your money's worth.
Do visit Jellyrolls at night and check out the Boardwalk entertainment.
Between the Boardwalk, the Y&B Club and the Swan and Dolphin, you have a lot of dining choices within walking distance. So take advantage.
Walking distance is a subjective concept at BWV. There is only one bank of elevators, so the lower number rooms are the farthest walk. But then, you are closer to DHS. If long walk is an issue, ask for a room near the elevators.
Btw, little bit of trivia since kook mentioned being able to see the Eiffel Tower. France is the only pavilion in EPCOT where they had to decorate the backstage facing parts of France, since they realized when building the Yacht & Beach Club that the backstage areas are visible to guests staying there.
One week from today and I will be there
