Disney World - What to Bring??

Wow what a bunch of opinions here. The only thing that hasn't been suggested is to hire a professional photographer. I will say this again based on experience at Disney. This will be the 4th or 5th time in the last 3 years. I will take the 5d3 this time because besides enjoying the park I would like to get some really good shots. All the previous times it was all about the child. I took the g12 on the belt and it worked perfect. When a huge storm came around we got soaked so didn't have to worry about protecting a big camera. Not only will u carry a camera but u will probably buy a lot of stuff so now u have to carry the camera and a bunch of stuff. Since I have bought all the princess u can buy I can focus on the camera. There is no right or wrong answer here. Hell just take an iPhone and really enjoy your time with the family.
