Karren, the desk staff at most hotels and motels have seen plenty of crossdressers in their time. The staff at the one you took the time to get out of femme mode for check-in probably were sharp enough to put two and two together and know exactly who Karren really was when you went out later. So, what's the problem? They probably know who you are anyway. They don't have any reason to give you any problems and plenty of reason to keep you happy for return business. You should go ahead and check in while fully dressed and made-up. Just hand them your regular ID and credit card (personal - not a company one), smile, and enjoy the adventure.
