For next years trip I am thinking about getting fanny packs for DD6 and DS10 to wear. We have discovered that giving them each money works well except that they are more likely than not to leave their wallets back at the room. I thought that by giving them fanny packs with their money, autograph books, etc, not only would they be more likely to remember what they want to take along but we may also be able to downgrade from a backpack to a few fanny packs. Has anyone tried this with kids this age and with what results? Also any suggestions on where to get kids fanny packs?
