I have a confirmed registration form 8/2-8/5 for a downtown hotel. I want to extend it to 8/1-8/5 instead. I tried modifying my registration to include the extra day and it says there are no openings. I am guessing everything is sold out but I am wondering if the system is confused because it can't change my 8/2 date to 8/1. I tried calling the Hotel and they have no record of me with a reservation yet and he was unable to tell if that 8/1 was available.
Is there a number or email I can contact someone on this?
