WAAAAYYYYY better than noodles - THIS is the ultimate float:

When deflated they weigh NOTHING and take up NO room, so they travel beautiful even in carry on. I never leave home without one if I'm going to be anywhere near water - and I'm known as the Imelda Marcos of water floats, so this is truly an endorsement.
