Someone posted on the forum a link to someone that makes a cover specifically to cover a packnplay. The idea behind it was to save constant cleaning with the idea you could take it off and wash and put back on. But it would also do the hide from others trick too. Forget what section the link will be under.

Wish I had more space in my room to allow more room between the kids but we work with what we have. Glad you found a solution.
