Replying to Questions about Lift Tickets/Where to go

Me and my brother are going on a week long vacation to Colorado two weeks from now in an RV. I am looking online at all the lift ticket prices and most of the places average around $75 per day. Abasin is the cheapest at $51 a day plus I found an online coupon for a $12 discount so it is $39 a day which is a really good deal. SO here is my question. Should we stay at Abasin all five days we will be skiing? Or should we suck it up and pay some of the higher prices to check out other places, and what places should we not miss? ALso, if anyone has any links or resources where I can get tickets at other resorts for cheaper.
