That wont work because what they do is put a crappy universal remote (that can't change modes)in the rooms to use and they keep the factory remote (which will change it)
Your best bet is to figure out the tv model # and get the right remote or try codes from here.

Or break into the hotel office and nab the remote lol
(don't do the crime if you can't do the time) don't do it .

haav I wanna go party with you I need some new equipment to fall into my hands . lol
