As others have said, the offerings are the same for both. Both club levels are nice, but there's nothing like staying RPC and being in the main building. If I didn't stay RPC, I would book a regular GV over SL, but that's just me. When I stayed in SL, I thought the lounge was kind of crowded and there didn't seem to be alot of seats/tables for the number of people. But with that said, the offerings were great. RPC is more spacious and the views from the lounge are beautiful.
