We stayed at the Summerfield Suites LBV in Sept 2000 on a long weekend trip (FWIW, we were placed there by Priceline). We all were very impressed. The suites are very comfortable and the hotel is nice and clean (we had a 1-BR King). The kitchen area was very spacious, the LR area had a table w/4 chairs and a sofa, chair, coffee table and TV. There was also a TV in the BR. The vanity/mirror was in the BR area separate from the toilet & shower (so one can get ready while another showers). The "Deluxe" continental breakfast is very good (you can get pay extra for a cooked-to-order omelet) and the overall location is very convenient to WDW.
The only minor thing even worth mentioning is that the walls of the suites are painted pink (think Peptol-Bismol). Must be trying for the Florida/Breezy look.
If you can live with the pink walls, I believe you will be very pleased with this hotel.
