If you need to save money and don't mind taxi-ing to the strip, stay in a 2 queen suite. Can sleep 6 comfortably because of a pull out couch. Shower and toilet are separated so its even more ideal for splitting with 6 people. Hint: Just say there will be 4 people in the room cause you'll have to upgrade to a larger room. Complimentary breakfast in AM.
It's a new hotel with a nice room, rooftop pool and gym.
