The Mrs. and I will be leaving on a cruise out of Port Canaveral in a week, followed by a week at Disneyworld (Key West). Generally, we alternate between Bay Lake Tower and Boulder Ridge, but since we will be just getting off a cruise, we opted to save a little and stay at Key West for the first time. I'm apprehensive about how far it is from everything, but I do like the ambiance at Key West. My wife and I are Disney Pro's, so we'll manage.
We have considered pulling a travel trailer down to Fort Wilderness, but it would be a pretty long haul, and fuel would cost a body part or two. We have also looked into renting one of those really big travel trailers and having it already set up for us when we get there.
Let us know how your trip goes, and if you like actually staying in a TT at FT Wilderness. BTW, when we go around Halloween, we usually rent a golf cart at Ft. Wilderness so we can drive around and look at how everyone decorates their campsites for Halloween. Some people do some pretty cool stuff.
Make sure you put the Valentine decorations out!
