At our house DS always put the same basket out each year for the bunny to fill. if that happens at your home, you could have to kids to take their own baskets from home to set out for the bunny, and pack, in secret, things in your suitcase to fill them. You could finish them out with a after bed time trip to the gift shop at your resort while DH stays in the room with the sleeping kids. I am sure they will have some specail things to add, including chocolate!
