Can you travel at night while she sleeps? That will make it easier on her but if you have to go during the day, as long as you give her time to play she should be fine.
I would practice at home in the pack-n-play before hand. Maybe one nap a day to start. That way if she has a hard time sleeping at least only one nap will be messed up.
Also make sure you bring many comfort items to make her feel comfortable sleeping out....her lovey, noise machine, etc.
As for your routine, try and stick to it as best as you can but you are on vacation so have fun and go with the flow. It won't be perfect, the routine that is, and when you get home you can fix anything that is not the way it use to be. We have a
Getting Back on Track Thread that will be helpful for when you return.
