Anyone have any recommendations for a good restraint system that would work well in random hotel rooms?  

Has the best quality that I've found.  4.5/5 stars on Amazon with 222 reviews

Have fun!

also use backpack / rigging / climbing clips for fast release and length extensions

A good cotton rope with no core (holds its knotts better) run under the mattress at the top and at the bottom of the bed tied to carabiners (easy release if needed).  Then carry with you some neoprene velcro strap cuffs.  They are light weight and will go into the shower with you if needed.

On doors, tie a triple knot in your cotton rope or tie a rope around a pencil/pen.  You need two.  Flip the knotted end over the door, flip the second one close or a foot apart - depending on how you like people to have their arms, and close the door.

 
This handy Pocket Dungeon my friend Ming created will be available in November - it has the door suspension tools in it.
