Marriott's Sabal Palms and Marriott's Royal Palms are both on the grounds of Marriott's Orlando World Center, just off World Center Drive, which becomes Epcot Center Drive. So they both have great locations. The main hotel at Marriott's Orlando World Center has numerous options for dining and drinking.
Sabal and Royal are among the oldest timeshares built by Marriott, but they're renovated every five years or so -- so they're always in good shape.
Each resort has its own pool. Both resorts allow guests to use of the spectacular main pool at Marriott's Orlando World Center. You can walk or take a shuttle to the main hotel.
Sabal Palms has two-story buildings with no elevators. Royal Palms has four-story buildings with elevators.
From Sabal Palms, it's a much shorter walk to the main pool than from Royal Palms.
Driving to Sabal Palms requires a long "backstage" road that winds behind the service areas of Marriott's Orlando World Center. Royal Palms is more convenient to the Orlando World Center entrance.
