According to betterbidding.com, this is how the Hyatt is listed in Hotwire.com:
4* Hyatt Regency
Amenities: Shuttle, Restaurant, Pool, Fitness, Hi-Speed Internet, Tennis, Business
OR
Amenities: Shuttle, Restaurant, Pool, Fitness, Hi-Speed Internet, Business
(same as Renaissance)
A 4 star for the MCO will either be the Hyatt or the Renaissance. I personally would be happy with either one. I know the Renaissance is not attached to the airport, but it is supposed to be very nice. They have their own shuttle.
EDIT: I looked on Lastminutetravel.com. If you search for airport area only, they Hyatt is listed as 4-star Orlando, 3.84 miles to the airport. Don't know why it says that, maybe to throw people off? But if you look at the photos attached to that one, it is the Hyatt. The Renaissance is listed as 4-star Orlando, 1.85 miles to the airport. I just checked 7/12 to see what I saw, and the Hyatt came up at $111, and the Renaissance was $89.
