I'm actually skiing the whole season in Laax/Flims...
What timeperiod do you planing to stay there? Longer then a month or just a week or two? What's your budget how much money do you want to spend (accomodation/food/party)? how many ppl are you?
Riders palace is for sure not a bad idea you can sleep there for like 35 swiss franks per day, but you can't cook there, so you have to go eating somewhere else (not rly cheap). for partying and lift access its for sure rly good place to stay.
To find a room for longer timeperiod is not easy, because they want you to rent them for the whole season most of the time...
here is a link to a backpacker in Laax (village) not as near as the riders to the lifts. but as said, there are shuttles which give you good access to flims or laax...
