@Alexandra316, yes I've found most of my guests book last minute, usually the week before and I agree, it wouldn't be worth going so low that you are basically making nothing once you factor in your time.
We just started in March, and have had pretty much a full occupancy rate since then, although May was slow. July and August have been great and I think September will be full too with people coming to see the aspens.
I am anxious to see what happens in winter, although really, in my place, winter is the most pleasant season imo.
Which other sites do you use? Right now, we only use Air, as they collect taxes for us in Colorado and we just don't want to have to deal with that. Kind of funny, as my partner is a CPA, but he's too busy at work to want to handle taxes from other sites. But, I am considering other sites as well at this point.
