@vandy - we have needed two pank not plays a few times and haven't had issues. This last trip we were able to get a portable crib
@BCV (the second kid slept in the pack n play that was already in the room) and two portable cribs @AKV (which could BOTH fit in the master bath of our 2BR - nice for nap time!). I liked the portable cribs much better than the pack n plays!
