When you book is it held and you pay when you check in...or is it paid in full at the time of booking?

They usually charge me right away once I book, been there a few times already, hope that helps

It depends on who u book through. If u book through a third party the funds are paid at booking and u still are responsible for incidentals at the hotel with your own credit card

Same for me. Charged deposit when I booked, balance once i got there. The also have a $200 incidental fee that they asked to hold on a credit/debit card "just in case".
