What do you mean by nice?
Nice to take your significant other to for a romantic getaway?
The Pheonix Desert Ridge & Spa is nice, if you like that style.
The JW Marriott Orlando Grande Lakes is good, too. So is the Ritz-Carlton there (but no points with them).
Rome Grand Flora.
Paris Downtown.
Nice to take the kids to for a big trip?
Fairfield Inn Anaheim Disneyland (right across the street, IIRC), the hotel won't matter too much if Disneyland is next door.
