Carrying as Little as Possible

One of the new trends that Disney seems to be promoting is the idea of carrying as little as possible. Presently your hotel card can act as a credit/debit card, and anything you buy in the park can be sent to your resort front desk for pick up. But they're not stopping there; right now they're testing a new system that changes your hotel card into a wristband. Magic Plus will be a wristband that may eliminate having to carry anything hotel or theme park related at all. The only thing I don't think it covers is the Fast Pass ride vouchers.

Assuming that the magic plus system is up and running, what else is important to carry with you on your Disney adventures?

Camera - Our choice of camera is going to be the Fuji XP. It's the perfect vacation camera because it's small, waterproof, and pretty tough. You can take it anywhere in any park without having to worry about keeping it dry.

Water - The big question we have is if it is necessary to carry bottles of water with us throughout the parks.  I'm told that you can find water fountains all over the parks, but are there enough to keep us hydrated, particularly while waiting in line for the rides.

Snacks - While we plan on buying one of the meal plans that includes a snack, I think we may also pick up a few granola bars to carry around as well.  That way we can pick our treats based on how much fun they might be to eat rather than how hungry we might be.

Bags - Whether or not we carry a bag while walking through the parks depends on our decision to carry water with us.  If we decide to bring water bottles with us through the parks then we'll probably bring bags to the parks as well.  If we only pick up water along the way, then the bars and camera can easily fit in our pockets.
