bk - When you call PayPal - and check back in with the hotel desk - make sure to see how many "pending charges" they put on your card. As I found out last week, I actually had more than one charge on my card. However, I did not know that until my customer service rep at my bank pointed it out - even though on my online statement all I saw was one pending charge. -It only showed up that way since they both came from the same merchant. -Consequently, I had to make sure that the hotel requested a refund for both charges.
*Btw, if you are still up, and they have a manager on duty, he should be able to easily void the initial transaction. It's a "Code 4" or "6" - depending on the Zon machine. It's a Void, NOT a Credit. -A VOID is immediate, a Credit is not. And since most hotels don't consolidate (that's not the right word) their charges until 3:00am...
