It bothers me more than a little that we haven't been at the lodge since about 2003. It bothers me even more that we haven't been to WDW since 2005.
That said, you've chosen the finest resort at the place. There are wonderful things I love about the Grand Floridian. And there are truly wonderful things about being on the MK side of the tower in the Contemporary.
But for an overall resort experience, the Wilderness Lodge is our choice time and again.
The lobby is overwheling, in a good way. The shop is very good. All three restaurants are good. Roaring Forks was my kids favorite in all of WDW when they were young. Not sure about the early closing someone mentioned earlier. Last time we were there, it was open until 12 midnight, although the grill may have stopped at 11. (I remember originally it was 24 hours, although the grill shut down at 12. It was great coming back from an E-Ride night at 3:30 in the morning and getting some chocolate cake and a drink
The boat ride is relaxing. It is sometimes not direct as you have to go by Ft. Wilderness first. The bus service is the biggest drawback. It's not that the buses don't come and they're not overly crowded if you are an early-bird, but they often stop at Fort Wilderness or even Contemporary, Poly or Grand Floridian on there way to somewhere.
Rooms are very nice. Not as big as the monorail resorts, but very nice.
The spring that turns into the creek that turns into the pool is wonderful. There are whirlpools and the geyser and the trail to the boat and the exercise trail and the marina and the bike rentals and etc...
The staff has always been wonderful.
You will like this a lot.
