I got an answer from totalrewards:
--------------
In regards to your email, if you are using 6 total rewards cards you must book 3 separate reservation. You are unable to add more then two companions on each hotel reservation.

Maybe you guys can help me with the suite thing...
Is there a chance that there is a suite on the strip with preferrably 6 queen beds? low budget as well? (meaning not more than 500 $ for the room per night...)
thanks
when I try to search @totalrewards properties they always say 4 guests max per room. So I am guessing 6 beds doesn´t work...
