Welcome to the Dis!
What do you want to do and what is your budget? WDW has options for all tastes and budgets.
Basic "flavors":
Value - Least expensive, small, fairly basic rooms, no sit down resturants, but expansive food courts. Theme pools, but no slides.
Moderate - Slightly bigger rooms, double beds still, usually 1 sit down resturant plus nice food court, more theming in the pool area and pool slides.
Deluxe - Most expensive, queen beds, most offer a daybed (sleeps 5), conceirge level rooms, 2+ sit down resturants, limited food court, closest to the parks, variety of transportation (monorail/bus/boat) except for AKL which only has buses, nice pool areas
Home away from home - DVC (a/k/a, timeshares)
Fort Wilderness Cabins - sleep 6, full kitchen, daily maid service, private cabins (some love, some feel isolated), basic "hotel" style pools, I dont think there is a pool slide,
Where ever you stay, you'll have a wonderful time!
