Hello Kathie, here is some info in regard to the Sam's Town Shuttle. They provide shuttle service from 6 different locations: Riviera, California, Fremont, Harrahs, Bills, & Tropicana. Here is a 800 number you can call and just ask for the recording for shuttle service. The Service from the Riviera starts at 9:50 AM and runs every Hour and 1/2 to Sams Town. Last shuttle leaving at 9:50 PM. Shuttle service leaving Sams Town starts at 10:30 AM to the Riviera with the last shuttle leaving at 10:30 PM. Hope that helps.
