We use the Kidco Peapod travel beds now instead of pack n plays. I bought them from
THIS store off ebay for $70 w/ free shipping and we have definitely got our moneys worth already. Plus, they should last us until the girls are 5 or so. Anyway, I'll be taking them as carry ons if they won't fit in the suitcase. Very light. I'd avoid taking a PNP if you can. So heavy and bulky with everything else you will need to keep up with.
