there are quite a few sites that you can search that will likely show you great hotels at the best prices available. check out the website BookMe and you will be able to compare prices on all the reputable travel sites in just a couple minutes. it s very convenient and will save you a bunch of time and money. Also, make sure you buy them online... otherwise they charge much higher fees for phone orders. good luck.
Did you check hotwire? I see hotels for around 70-80/night. Alternatively you can try staying at places a few miles away/
It s Big Bear, what did you expect? Nothing is cheap there.
