If you travel for Christmas and “believe” in Santa, how do you handle gifts?

We’re going to be flying cross country for Christmas with the ILs. The last time we went at Christmas LO was a baby. DD heard me tell MIL that we’ll be there for Christmas and she wants to know all the details of where Santa will bring gifts.

DD is already starting to question Santa and logically I’m ok with her figuring it out but part of me would like one year where both my kids (DS is 3) believe.
