Checked in at the small VIP area at the RIO. Yes, it was quiet and away from the bustle of the crowd but it was rather stuffy. The lobby is not that big (compared to the other huge hotels in LV) although still busy on a Sunday night.
HUGE rooms, like the wet bar, can sleep 6 easy. Great view of the strip. adequate parking. Shops are ok but not high-end. I like the fact that it is away from the strip where you can experience the craziness of LV and still have some down time.
Servers also double up as performers every 15 minutes (sing and/or dance) on small stages set within the casino floor. Awesome outfits custom-made for each girl. Hot stuff ...
RIO is ok. Nothing to rave about, but off the beaten path if you want to enjoy a bit of Vegas without going really crazy.
