Traveled for work. First time had random bar charges on my final bill and the second time they charged me for a check in that was cancelled. (Plans changed and i was there a week earlier than originally planned. Cancelled the reservation for the second week and was charged a no-show fee becuase the system never updated). Even though i had the confirmation number i had to jump through hoops to have it corrected.
