Be carefull with sneaking people into hotel rooms that don't belong there, the staff doesn't like that at all b.c that means they are losing money. SO that means you have to be VERY quite at night. Just a friendly warning b/c I have been in hotels where people get kicked out of rooms, it doesn't look fun at all, that and you have to sleep in a car or on a bench.
Just an Idea from someone uninvolved
