We've stayed at the Hyatt the night before our flight frequently. It's nice to relax and realize you're already at the airport. When you stay at the Hyatt, you can arrange for assistance by the hotel bellman to the airline check in desk. If you want a last-minute taste of vacation fun the evening before your plane leaves, there are some nice shops, restaurants and a large food court just steps from the hotel. My favorite shops at the airport are Disney, Sea World, Universal and Kennedy Space Center.
