He doesn't sound normal to me but that doesn't mean he isn't. I don't like guys who continually text after "making a booking", why not get that all sorted out before a booking is made. Maybe im being too fussy, but time will tell, but the continual texts and the boasting of the size of his manhood is a definite TW trait.
He says he wont be in room till after six so i would just take it a step at a time.
I would do the usual security checks, even calling the hotel asking if Mr X has arrived even when you know he hasn't. You can always say you'll call back later. If the hotel sounds funny about things it may mean they don't have a booking for him but cant say. This you may have to judge for yourself.
What you don't do is move out of your home before you speak to him to him in his room at the hotel. If you want to get ready before this then that is up to you.
Good Luck.
