Hi there. I'm about to head off to my first Wilderness Lodge vacation!
First off it's really important that you have a clear understanding of how very, very, very, very, very different the Wilderness Lodge is from Fort Wilderness!
The Wilderness Lodge is your standard Deluxe resort. It's incredibly beautiful. The rooms are intricately themed and some even have bunk beds in a commitment to theme. The dining options are also great. They have one signature restaurant, Artist Point, one quick service location, Roaring Fork, and one table service restaurant, Whispering Canyon Cafe. Many people enjoy WCC as the waiters employ fun antics similar to those of the waiters at 50's Prime Time Cafe. There is a beautiful pool. As far as transportation goes, there is a boat launch to MK and bus service for the rest of the parks.
Fort Wilderness, however, is a camp ground. So don't even look at it unless you want to go camping!!! It is very, very, very large. So large, in fact, that they have an internal bus service. I'm not too familiar with Ft. Wilderness, but I know that it's home to Trail's End (an *awesome* breakfast and dinner buffet) and the Hoop-de-Doo revue (an *AWESOME* all-you-care-to-enjoy dinner show!). Like I said, I don't know too much about it, but that's what I do know. I would assume they also have quick service locations, and I know they have activities like petting zoos and horse rides. Campers at Ft. Wilderness are entitled to the same perks that resort guests at WDW have, such as free transportation, eligibility for the
Disney Dining Plan, access to parks during EMH, and more.
ETA: I should add that Ft. Wilderness DOES have a limited number of cabins available for families. They're quite large and can house up to I believe 8 people? Other than that, if you want to stay at Ft. Wilderness, you'll need either a tent set up or an RV.
Hope I helped!
