Sounds like you already know what you want with either CCV or BC. Our favorites are VGF or RIV. We got an incredible deal on GFV direct and their dues are historically much lower than most other resorts - making them one of the most economical as SAP. More economical than SSR. Plus no resale restrictions.
The split bathroom set-up in VGF and RIV make them just as convenient as a 3rd bathroom (if not more so). You essentially get 4 different bathroom areas in the 2 bedrooms for each of these. Location, resort amenities, onsite dining, etc. were all really important to us. MK is the one park at which we spend at least 2 days every trip, making the location of VGF really appealing. We also just love the grounds, vibe and relaxing nature of both of these resorts.
Have fun choosing!
