Recently learned that Rio was hosting August 9-13 and decided to try it along with partner. Never been to one before. Got tickets for general admission, Saturday the 11th and Sunday the 12th. Is it reasonable to try to make a 9:30pm Saturday performance of VIVA ELVIS, or will we be too tuckered out? Any clothing suggestions, other than wearing costumes? Any advice on what to see or ways to maneuver? Any helpful suggestions appreciated.
