Hi there, Chris!
You actually have a couple of different options for rooms that provide two bathrooms. The rooms are also designed to accommodate at least six guests, so there should be plenty of space to spread out, even with four adults.
The first place I recommend is
Disney's Art of Animation Resort. This resort pays homage to some of Disney's most beloved animated movies. This resort features sleeping for up to six adults, with a queen sized bed in a master bedroom, plus two convertible options that each sleep two people in the living room (a pull out sofa bed and a table that converts to a bed). You'll have two full bathrooms, plus a small kitchenette, which is really helpful for grabbing a quick bite for breakfast or a snack.
Another thing to consider are the
Disney Deluxe Villa Resorts. These are definitely home away from home type of accommodations, and some of the 1-bedroom villas have two bathrooms. The master bedroom has a king bed, then there is a pull out sofa in the living room. The deluxe villas with 2-bathrooms in the 1-bedroom include
Bay Lake Tower at Disney's Contemporary Resort and
Disney's Animal Kingdom Villas - Kidani Village. All of the villas with 2 or 3 bedrooms will have at least 2 bathrooms.
Disney's Coronado Springs Resort has junior suites that offer two bathrooms. This is another great option for your group.
Wishing you an absolutely magical vacation, Chris!
