Not familiar with that Co, but most are all the same. Pretty expensive commitment and you are stuck with staying at their resorts. Most of the best sites are taken for usually 2 week max slots so unless you want to do that they are not of much use. But hey, go do the 2 free nights which will require their tour of course and "just say no" when they bring out the legal pad. Then find out how much real camping you can do all over this country staying in State and National Parks for half or a third of private campgrounds, have spacious sites with privacy since they are not for profit, and not make a big financial upfront outlay of cash to a Co. like this one! Travel far and wide and enjoy seeing and discovering new areas.. not the same old place.
EDIT-- After reading all the complaints to the BBB on this Co, RUN-- DO NOT take the 2 day free stay.. It looks like a disaster and a scam ! No one needs that aggravation after laying out big $ in advance.
