That seems like a hell of a deal - $132 for a suite at the Marriot?? That's about as close as you can get to RR as well .. right off 6th Ave. It's funny they consider that to be Golden. I would call it Lakewood. I agree there's not much going on in Lakewood but Golden is a cool little town. You can even visit Coors
I usually take the hotel approach of reserve it if there is a good price and then cancel if you don't want it later. Easier then trying to find a good deal at the last minute. Just have to remember to cancel!
TownePlace Suites is the "lower end" of the Marriott chain but totally adequate and I like having a kitchen -- saves a lot on food & drink! They have some sort of free cheapo breakfast but we were never awake early enough to see what it was.
