The only problem with using someone elses room number/password is they will not be able to use it after that until they go thru the hassle of having it reset.
You can only use 1 login at a time for a room number. My wife and I had wifi last time and we would have to log out, so the other person can log in. The wifi is very spotty around the resort. It wouldn't work in our 5000 block room, so we had to go to the front desk area to get online.
