I always take my friend with me and they don't have any problem with it at all.. And there is never a fee.. The lady said we didn't even have to tell them unless your wanting another bed..
I am sure they would accommodate the second person but I would contact guest services to find out if there's any additional fees at exactly why ethics guidelines so you don't get tricked into additional cost remember even valet it supposed to be free but you tip
As long as its just one adult it should be fine.
