Forgot to add - fire code depends on room size. Some may have one double bed with one foot of space between the bed and the wall. That room will have a fire code size of two.

However, if you can find a room with two double beds (you'll rarely find one that has two queens), the fire code might be four.

And the larger the hotel, the less of a chance they'll check. Just keep your heads down and don't get too loud or crazy.

PS. the words "sitting area" or "work area" are your friend because they mean floor space.
