I spend most of my life in hotels. Never a problem. I do rent a room for a few hours at airports all the time get a wake up call so I do not miss a flight. No one ever said anything. Most ladies will come to the room unless there is a controlled floor. A lot if hotels have exceutive floors where you need a room key to activate. If so you. Leave an envelop with the key in for your SP at the front desk. The SP asks if there is an envelop for them at the front desk then comes up. Or go and meet them in the bar before hand. For some SP they like that so they feel comfortable. I like it if the SP will sedice me.
So have fun with it and enjoy the experience.
