amazing graduation present for your kids (or nieces/nephews)! Every year write them a letter until they're 18, and put a small amount of money in it, then when they graduate - give them all the letters + money!
Travelling with young kids made easy: Put an entire outfit (including undies and hair accessories) in a ziploc bag. One bag per day. When you get to the hotel, put the bags in a drawer and they can pick one per day
