When it comes to holiday travel, I find it is difficult to stop Mom and Dad from going places. Apparently the draw of family is even stronger than the draw of a kitten pressed up against you in bed -- and that's pretty strong! But that still doesn't stop me from trying to keep Mom and Dad home.
I highly recommend sleeping on or in their luggage. In this case, I'm doing both. Mom and Dad like their orange Eddie Bauer duffel bags (easy to spot and they hold a lot). I like them for a nap. So even if they force you off of the bag so they can pack at least they'll be traveling with a big hunk of Jasper hair so everyone knows who they belong to. Thankfully it looks like Mom and Dad are home for a while after traveling for Thanksgiving. Hopefully your beans are staying put too.
