I just bought the Baggallini messenger bag for our Dec. trip to WDW. I used it last week for a day trip to Chicago and found it to be very uncomfortable. It really hurt my shoulder/neck. I may have packed too much stuff in it - had two bottles of water, guide book, etc. I thought the Travelon bag looked a little small - we will be traveling with 3 small children. So, I am starting over and looking for other options too.
