Re: How will Santa find us if we travel over Christmas?
We do the same thing my parents used to do(until we ALL stopped believing) was make sure Santa presents were smaller items so we could take them. Presents from siblings & parents stay at home & we either open them before(then they have something new to play with on the way) or when we get home.
As kids got older & they could process the thought behind it, Santa would leave a note that the presents were at home. There was ALWAYS at least 1 thing from Santa under the tree wherever we were though.
You could also send things ahead IF you're taking gifts for other people & will have room on the way home.
