What I did was use our old towels as well as stuff them in front of the vents.
It is horrible staying in a hotel that does not have control machine control, then nicer hotels use a wall mounted control machine that controls just the room Heating as well as Air Conditioning. This way the client can decide their own heating as well as air conditioner without affecting anyone else in the hotel. This form of zone control is efficient, effective as well as allows the guests to stay in ultimate comfort, but you never think what you are going to get in a hotel though. The most recent locale I stayed in had the brackets for a control unit, however it was empty, at 1 point the hotel had Heating as well as Air Conditioning devices as well as control machine control in each room. They then updated to central Heating as well as Air Conditioning all controlled by 1 control machine out of reach of the people staying the night. I don’t care for it when that happens since I get freezing easily. Of course I was staying in the hotel while in the summer. The hotel cooling unit was on super low as well as the air blasting out of the vents was horrible. The vents were entirely along the baseboards under the window. What I did was use our old towels as well as stuff them in front of the vents. There was nothing I could do to turn off the AC, so I simply resorted to blocking it. I can’t imagine how bad that would be for the Heating as well as Air Conditioning bills. I did not care though, I wanted to not freeze to death, however for several days that AC unit did not get to control the room temperature. If there would have been a control unit, the hotel could have saved money by not providing A/C for our room.
