If it's the only place available in that area, and you NEED to stay there... then you pay it. Who cares what they call the fees, in the end, the total is the total.
We pay, what I consider to be, a really high amount to stay at the KOA in Laramie, WY sometimes when UW has home football games. We're basically only there to sleep and then head home the next day. It's not a nice park, we're like sardines, and it's right next to the interstate. But we pay it because it's the only park in Laramie pretty much, and it's still cheaper than a hotel. Supply and Demand.
