I stay at Laquinta which is pet friendly as well (I always bring my dog when I travel). Every show that I've gone to - I bag the snakes that I'm bringing and then put them into a duffel bag. I have a 40 quart Sterilite and a human heat pad with no auto off feature on it.
I plug that in, and put the tub under the sink with the heat pad on the lowest setting and then put the snakes (still in their bags) sort of 1/2 on and 1/2 off the heat.
Keeping them under the sink keeps them out of the direct air flow of the A/C as well.
We put up our do not disturb sign for the entire visit so that we don't have maids entering the room. When we stay for more than 2 nights, the 2nd day they hang fresh towels and toiletries on the door.
Hope that helps!
