I think fepenn has a good suggestion - get two regular pack n plays. You will want two later on when they are older and you need a portable place for them to nap. When they are older they will be too heavy and too big to share the twin pack n play - even if you take the bassinets out. Don't bother with just getting regular bassinets - you won't ever use them again - at least a pack n play you will be able to use as a play pen or a napping spot later on.
We ended up buying our first pack n plays when our boys were 1 and we bought two because 1 doesn't have a high enough weight limit and they would never both fit comfortably in there. They work out great for napping at other people's houses!
