The reason the rooms are hot is that they have motion detectors and if no one is in the room it shuts off the air conditioning.
I hope you move a lot in your sleep or you will have problems then as well.
I am thinking of bringing a fan and something I can hang on a chair that the fan can make move.
Pretty rediculous to have to go to such lengths, but I have MS and real problems with heat, as it is I have misters, shaded canopy and cooling devices on my ECV for when I am out and must stay out of the sun.
Hm, I wonder if an occilating fan moves enough by itself to trigger the sensors? thats a thought too it would also help move the air around.
