Yeah - the "resort fee" business is pure BS. I don't have the body for going out and laying by the pool in a bikini, and if I did I would order a pink lady anyway
(I'm kidding, I'm a 50s+ man).
But the "resort fee" is a "just a charge for you because we have a pool whether you used it or not." - insulting, really.
The thing that killed me was hotels charging you $20/day to park your car! OMG. When I was kid all of our vacations were in the family car. No place we ever stayed would charge us to park the car. Insane.
