If you have 3 children, you have to rent two hotel rooms. Also when your kids bedtime is 7:30, having 1 room with two beds just sucks.

This really depends on the family. I had 3 siblings and we traveled a lot. When we no longer all fit on the same bed, I got a folded-up blanket on the floor. Eventually my sister decided she would rather have the floor. My brothers are awful to sleep with...

They normally force you to buy 2 rooms now, that didn't used to be the case.

They've always frowned on it. We had a regular procedure called "heads down!" in which all children or occasionally just three of us would duck down so as not to be visible in the car from the window of the motel office. When my brothers and I travel together now we still do it (mostly) as a joke.

Having stayed in a motel a lot over the last month, I'm pretty confident most parents could get 4-5 kids into most hotel rooms without management being the wiser.

Normally where? I've never had a problem getting 5 to a room with a small fee and an extra cot provided.
