If you are moteling I've never seen one that didn't have both iron and ironing boards. Most are in the room already, but smaller motels have them at the desk, all you have to do is ask.
If you make your own carry along board be very careful where you place them, I was in a class once where a home made iron surface ruined the surface beneath it. Practice on it at home
and see if it gets hot or steamy on the underside.
