where are you staying? Most of the hotels have pak and plays.You have to pick up a few pack and play sheets however, They just give you a regular sheet to tuck under. How old are your twins? we use a air mattress for them. But, I also lie down with them. I have seen several people on these boards have rented from A babys best friend website, Sorry I don't have the link. They rent full size cribs, and people seem to be pleased with them.
