I second many of the ideas already mentioned. Since it does appear you'll be there at the holidays as drusba mentioned, make sure to visit various resorts for their decorations. You can hop on a boat for the Wilderness Lodge which has the best decorations given its setting as a Northwest lodge. From there, I highly suggest you walk to Ft Wilderness (via paved bike path, about a mile one way) and take in the holiday decorations there, as well. A lot of the RV owners really put on a show. They're a hidden gem. Grand Floridian also has elaborate decorations. CA Grill is good, but it can be noisy at dinner if you're wanting a quiet, romantic spot. We prefer the Sunday brunch--it's tough to get but well worth the effort if you can. Obviously, the ability to walk to MK (and the bus stops there) is a huge plus, and you have immediate access to the monorail. Definitely take advantage of TOWL. Get there 45 minutes early, grab a libation, and then stake out a spot on the deck. You can still watch it even if you show up 10 minutes ahead of time, but you'll likely be stuck toward the back of the viewing area. If you have a lake view, chill a nice bottle of bubbly or wine, and one evening, be sure to make time for the EWP. You will have an excellent view of it. The pool at BLT is nice enough, too, so take a plastic glass full of your favorite beverage at night and hit the hot tub by the big slide. Depending on timing, you might catch EWP from there, though I doubt you can see much; still, you'd be able to hear it.
In short, we've enjoyed all our stays at BLT. Our home is VWL, and it's still our preferred place to stay. However, BLT makes a strong case for being our second favorite resort.
