we are planning on DD 13 months to fall asleep in her full recline stroller when we are out and just wheeling her in. We'll have the pack n play set up just in case, but doubt she would sleep sound in that. It's too unfamiliar. You should do what you're comfortable with, bring the crib it will be fine. That is not a lot of disassembly. Just think when parents re-use the cribs for their other cribs, it's taken down, put back up, taken down, moved in another room, etc. My DD's crib has metal threads that the screws go into, so there would not be any wearing down. Do what you think will make your vacation run smoothly. Being up all night isn't fun. I tried to get DD to nap in her crib, she was tired enough that she looked around and went to sleep, but she napped 20 minutes and normal time is an hour. It was because she wasn't used to it. Happened the next time we tried to.
