There were none available at BWV when we needed them, but that was almost 3 years ago, so things might have changed. We had a 5 out of 7 chance of getting a one story GV but were not lucky. We ended up putting ironing boards horizontally across the steps between the railings, one at the top and one at the bottom. They were low enough that adults could step over but little ones couldn't. We had plenty of ironing boards available because we also had a 2 bedroom lock off and 2 - 1 bedrooms.
