We are heading back to WDW this December. I've always been in June and carried a fannypack with a water bottle holder. This has always worked very well for me. I'm planning ahead for cooler weather in December and know that we'll need to take gloves and jackets. I bought a small sport bag that I can carry on my back. My question is this: What do you do with a backpack when you're on a ride. The fannypack was never a problem because I just wore it on my waist on the rides, but I'm not sure what to do if I have a small backpack.
