Try Lake Buena Vista Suites. Mouse Savers site often has great rates offered here. Standard rooms here have two queens in the bedroom and a pull out double bed in the sofa in the living room area. They also have a mini fridge, microwave, coffee maker and two TV's. Rooms sleep a max of 6. They're often in the $89-$109 range. They come with a very nice free breakfast. No parking or resort fee either.
The Caribe Royale is also very nice. It's a bit more expensive. Has a better pool area and no free breakfast. Same type of room set up at LBVS.
