I just did my fifth solo trip this past Nov/Dec; 8 days, all resorts, no parks this time.
Since all the resorts are decorated for the holidays, you get the best bang for your buck. But I really discovered a lot more about the resorts this time, because I wasn't so rushed getting back from the parks and dashing off to dinner.
I enjoy having a drink before dinner and after dinner, so I suggest:
Territory Lounge at WL, as a matter of fact, you could make a meal out of their snacks. Very low key, don't have to dress up, great atmosphere.
Do the water taxi loop from DTD to SSR/OKW/POFQ/POR and try out their pool bars in the afternoon or stroll the grounds.
Do the GF/Poly/CR loop and have a drink at the Wave; again, great atmosphere, good drinks.
Hang out at DTD and try out Raglan Road; sit at the bar and have apps and they have evening entertainment.
Also, Paradisio 37 has fantastic apps and great margaritas.
Go to the spa at SSR and have lunch on the patio at the Turf Club afterwards. The food is fantastic. You can watch the water taxi go back and forth to DTD and the golfers walk over for a snack and a drink. Lots of company.
The water taxi ride to OKW is long and meandering; try out Olivia's especially if you can manage to snag a table outside on the deck. Another place to people watch.... the food is fabulous.
Go to dinner in some places you wouldn't normally try; I did Sanaa for the first time last year and loved it.
Check out the nightly entertainment on the BW, eat at Kouzzina's (my new fav next to Sanaa) and then get some candy at Goofy's right next door.
Definately get out there and really discover the resorts and their restaurants; the atmosphere is so different than the places to eat at the parks.
