Okay Bees, I need advice!

I know that when baby comes, we'll be visiting my parents, Hubs parents, grandparents, etc. and we'll need a place for the baby to nap and/or sleep over night if we do a weekend. I'm just curious if people prefer a Travel Bed or the Pack 'n Play (or something else entirely).

Here's the two I've been looking at:
