When I go to my TR to make a reservation, and it shows a night is partially comped, but still shows the price as $0... Am I going to be charged something once I check-in? I have a room I booked way back in October for Superbowl weekend. 5 nights at Bally's, believe three of them showed up as $0. Finally decided this week I'm actually taking this trip, but will probably have to reconsider if I'm in for bigger hotel hit.
Don't worry about it. As long as the balance shows $0 you are comped. It is a weird quirk in the booking system.
Sometimes it means certain levels of rooms are comped, but other have a charge. Or, it seems that way. When you go to the actual reserve page, it will show you the charge.
Never had to pay room taxes or any other fee on a comp room with CET in Vegas and I've many times seen the "partially comped" when booking online. As long as the balance shows $0 then there will be no charge for the room.
