A look at the Paris hotel website will show you, in a view of the rooms, that the beds are built on a box support. But, if you bring along a drill, everything should work out.

at both of those hotels. Instead of slipping the rope under the bed (impossible), I just slide them between the two mattresses. I am available to demonstrate in your room if you invite me over. Free installation included with purchase ;- )

There's bars under the base frame to support the mattress. You'll have lift the mattress to get to the bars and tie them there. There's four bars, one at the top, one at the bottom and two in the middle.It's a hassle but I think most hotels have frames like that. As for the Paris I've never tried them there so I wouldn't know, sorry.

Maybe we will just bring the hog tie restraints and rope to play with, by the time I move beds and what not I won't have any energy to be tied up!!!!!!  lol
