Hi,
We vacation every Christmas and the entire family comes along....like all 20 of us (from a few months old to early 70's), sometimes we have a member or too opt out for this or that reason but.....as a family, we always give gifts to each member of the family, even if its something small, as its the thought that counts!
The older children understand that each year it will be a small Christmas due to the vacation but they are all right with that and have said numerous times they would rather vacation at Disney then have a ton of expensive gifts and not go.....we always find that Santa leaves a few presents (its always one big one and two or three little ones) at home under the tree.....we take along a garland filled with lights and a small tree (complete with lights (that have been twist tied on) and ornaments) along to make it more festive because we found it difficult to decorate the palm tree in our villa and make it look like a Christmas tree....lol....(the kids love to hang the ornaments after we get settled in) and we bring each family members stocking....The next morning, each family member finds a few little things in their stockings from Santa. The adults find one thing under the tree from Santa. The children find one nice thing and a few small things under the tree from Santa. Since Santa knows that we are all on vacation, he leaves their presents at their homes and drops a few off at our vacation spot so that they know Santa was thinking of them and did not forget them. And with 20 family members (sometimes) there, they have an additional 20 small presents too......it has always worked out great and everyone is happy, even the bigger kids!
