My recommendation is that you consider how well your child sleeps in a pack n' play. Has your DD slept in one recently for overnight sleep, not just naps? Is she generally a good/sound sleeper? If so, you can probably safely go with the pnp. Just bring your own sheets so they have the familiar scent--and so you know she won't have any reaction to unfamiliar/industrial grade detergent. Actually, you can even buy, for about $50, a small foam mattress, about 2-3" deep, and put that in the pnp for comfort (otherwise it's pretty much a piece of cardboard with a thin foam layer over top...firmer than ANY firm infant mattress out there, for sure!!) It would fold in half to fit in a suitcase, if you're not driving.
Having said all that...with DD, who was 12 months at the time, we rented a full-size crib from A Baby's Best Friend, brought our own sheets, and she slept great all week. With DS, just last week at age 7 months, we decided to chance it and go with a pnp with the extra mattress I just talked about (got it at Buy Buy Baby, it fit the pnp pefectly). He slept horribly all week long--up 4+ times per night, and of course you can't let them cry in a hotel room. I wish I had tried sleeping him in the pnp for a few nights at home before the trip. Either he'd have learned to sleep well in it, or I would have learned that he was going to sleep horribly and I would have rented a full-size crib!!!!
So, like I said....know your kid! Try her out sleeping for NIGHT SLEEP in the pnp at home. If she can't do it at home in her own familiar surroundings, you might just be better off renting a full-size crib. If you value your sleep, that is!!! FWIW, we had no trouble with ABBF. I'd just bring my own sheet/bedding, for familiarity's sake.
