You will probably get more responses on the Orlando Hotels and Attractions board since Buena Vista Suites is not a Disney resort.
We stayed there is April, 2002 when my daughter's HS softball team played at Disney's Wide World of Sports. The suite was large and clean. The living room had a table, 2 chairs, sleeper sofa, chair, tv, small fridge, vcr, sink, coffee maker and a microwave. The bedroom had 2 queen size beds, bureau with 6 drawers, armoir with an iron and ironing board, tv. Between the bedroom and living room was the bathroom with toilet and tub/shower on one side and the sink on the other side.
They have free breakfast every morning. The pool was average size, not heated when we were there is Mid-April. There was also a spa. The hotel is located near the parks, DTD and the Crossroads area and I-192 Kissimmee.
