ron808 -- funny you mention fannypacks...not very long ago on the Disney Tips board there was a large thread about fannypacks. I just can't do it...even at Disney! (Many people stated they aren't normally fannypack people but they use them at Disney!) My backpack has been to WDW, Panama Canal Cruise, Caribbean Cruise and now DL!
And I'm sure labguides wouldn't want to carry baby food in a fanny pack....fanny pack + baby food + ToT (or Screamin or Space Mountain) = MESS!
