I've learned that these things are generally much harder on mama than baby. At such a young age, they are pretty go-with-the-flow. If she's used to her sleeper and its easy to bring along, go ahead, but she'll probably sleep just fine with you next to her, wherever that is. As far as diapers, it sounds like it will be quite a whirlwind trip; I'd probably just go with sposies. I think these are exactly the times they're best for.
