If you're staying in the Ft Wilderness Cabins, are you booking a golf cart too? Honestly I strongly recommend it - it makes the stay so much easier and more fun. Just getting to the main bus stop to head to parks, or the boat docks to head to MK or the MK resorts is so much nicer when you can just hop in your cart and buzz down there and park...vs taking the internal bus around.
I usually do a fair amount of premium dining when I go to Disney - it's easy to justify since even a quick-serve burger with fries and a drink are over $20...since nothing's cheap at Disney, might as well go with the good stuff and splurge anyway!
Bull and Bear is excellent - not technically a 'Disney' restaurant but nestled into Disney property...Capa also even though it's in Golden Oak, it's not technically a Disney resort. As for Disney restaurants that have been my regular go-tos and favorites - Jiko remains tops for me - always a fantastic meal and service and experience. Topolino's at Riviera and Tapas at Gran Destino are both solid choices, great views too. I enjoy Steakhouse 71, even if it's not quite at the Signature level, it's still a regular pick for me and solid bargain as steakhouses go. I haven't been to the Disney Bourbon Steak - but the one in my hometown area is excellent so regardless of some mixed reviews I'd have high hopes when I try it. Yachtsman Steakhouse has remained a solid choice over the years and I still go there every few years. I've found Tiffin's in Animal Kingdom to be consistently good, with some nice creativity in the dishes and flavors. Monseur Paul has been excellent - though I sometimes have to watch the menu changes - I don't eat any seafood and they tend to be very seafood-heavy - though they've allowed me to go with two meat courses in lieu of the fish course.
As bars go - depending on what you're into,
Geo 82 is a very nice, high-end adults only bar and the liquor selection is very premium - some seriously aged boubons and scotches, tequilas, gins from all over the world, as well as traditional mixed drinks and cocktails.
Disney Springs is always a great choice for a big mix of restaurants and bars - celebrity chefs have been popping up there a lot lately - not many 'signature' dining spots, but some really good food and great bars (Art Smith's Homecomin', Frontera Cocina, Jaleo, Morimoto's, Boathouse, and Summer House are all solid places I frequent often.
