I haven't had an issue using RA, but have not made a reservation since Dec. OP said he didn't see this problem in Dec, but it's there now. So, I will pay particular attention the next time I make reservations.
I had to pay a $17 cancelltion fee when I canceled a reservation for a park in Fl in Dec. I was "OK" with that, as that was the conditions of the reservation when I made them. I actually don't have a real problem with it, if it helps control folks who lock up all kinds of sites until they are able to decide to stick with the reservation or not. I don't know how much that occurs, but Im willing to bet quite a bit. Im learning that is the game, in particular with Florida sites, so I may have to play that same game, reluctantly.
