For the poster that wrote they put a pending charge of $500, etc. on your account for the resort max. spending limit, they do not. They authorize 1.00 on your card to see if it works. The card is not charged until you a. reach your spending limit ($500 at values, $1000 at moderates and $1500 at deluxe) or b. you check out.
As for the problem with not being able to charge anything once you reached your limit jel...we were almost at our limit when inquiring at the front desk about our room charge totals in the middle of the trip. She told us that they re-set the computers at some point in the day(can't remember what time) and that if you are at your limit or close to and the charge you are trying to make is over what you have left, it won't go thru. I think she said this happens at around 3pm, I can't be sure though. We just had them go ahead and charge our card the amount on our folio and reset the limit. That's probably what happened with you.
