With the price being so reasonable we always have it. We do not go out of our way to seek a PA park out( the cost of gas can eat up the savings) but certainly use it if it's convinient.We have been to parks that allow us to use at any time just to fill spaces. We have been to parks that will strickly stick to the rules even if they are not busy. We were able to use it on weekends. It seems that the rules are not always enforced. We have stayed at some parks I've thought were shabby but I've stayed at non PA parks that were shaby and paid full price. In the time we've had it I know we have gotten our money back many times over( having said that there were years we never used it).Shorthly after we got it we attended a PA Rally and was treated so generously at such a low cost I feel I should patronize them for life. Great people to deal with.
