I'm vacationing with my neighbor and friend. I have not gone on a long vacation for some time (my husband only likes to hunt and fish). I love things like the extraordinary. I am worried that my friend might not be able to maneuver the ladder/steps to the tree house. She has had a knee replacement and is a little heavy. Please let me know what you think. I would have to sleep in the loft, I'm quite sure even tho' it is the bigger bed.
