We brought a cheap pair of rubber doorstops that we purchased at Walmart and used them. The doors might have stayed cracked with a trashcan, but I doubt they would have stayed fully open (which is what we wanted). Can't say if the host would have provided a pair of them or not. If it would be a crisis for you if the doors didn't stay fully open (which it would have been for us for one kid), then go to the dollar store and buy a pair. Better safe than sorry.
