I used biddingfortravel.com. The Hyatt used to be the only 3.5 star listed, but it looks there has been a revamping of the system that Priceline uses, as there are now other a total of 6. I have also gotten the Marriott Airport hotel and that does have a free shuttle. You can check out the other 3.5 * hotels on the Interim Orlando Hotel List on biddingfortravel.com
