Kristi,
There are several good options, but let me give you two choices, with reasoning behind them.
I think that for a wide array of ages, with no really small children, the best choices are these;
Deluxe:
BoardWalk Inn or
Beach Club
Moderate:
Port Orleans (
Riverside and
French Quarter)
So I picked for the Deluxe category the combined resorts of the BoardWalk Inn and the Beach Club (as well as Yacht Club, for that matter). First, they are ideally located within walking distance of both the Epcot World Showcase and the BoardWalk for convenient nighttime entertainment. If you have a lot of swimmers, then the Beach Club get's the nod. Also, both the Beach Club and BoardWalk have Villas, meaning you could get some accommodations for larger groups.
So what if that is too steep for your budget? Then I would opt at the moderate level for the Port Orleans resorts. That way you are all a boat ride away from Downtown Disney, again giving you convenient nighttime entertainment for most ages.
I hope that this helps! Write me back if you need more help!
Have a magical vacation!
