Nobody is going to ask you anything there are plenty of people visiting the hotel all day long just use your intelligence don’t dress in an obvious manner be relaxed if you are not used to hotels that is simply in the mind. No member of the hotel staff KNOWS the identity of EVERY booked in or reserved guest. Just walk in like it’s a department store and you are going to another floor. If chall need just be polite and relaxed there is absolutely no confrontation involved the issues and worries are all part of your guilt at cheating there is NO neon sign flashing above your head saying ADULTERER enjoy your day / evening / night. Don’t worry.
