Hello Oilman.
We stayed at Buena Vista Suites for a week in March and were very pleased. Rooms were very clean and adequate in size (though not as big as I expected). Nice enough pool & hot tub (I've heard you can use the Caribe Royale pool next door, but we didn't have time). Full breakfast buffet -- pretty good quality, fair selection -- eggs, breakfastmeat, potatoes, pastries, etc. We did not use park transportation. We would stay here again. There were 4 adults & 1 child sharing a suite. Do a search on this board -- there have been several posts regarding this hotel.
