Play a card game, cook together your favorite meal, bake cookies, play hide and seek, go on a long walk, take a bus ride or ride the incline. Being together is the best gift of all. Crowded indoor play centers are not the only ways to have fun. Old school art projects and making your own dance club are always great. I would try to avoid money on messy wasteful activities that will take tons of clean up- most kids hate housework.
