This has been a quest I have been on for some time. What is the perfect theme park bag. I have spent countless hours trying to find the perfect balance of space and lightweight. I have purchased mesh backpacks, cross body bags and fanny packs (my wife hates fanny packs). I think I have found the perfect bag. The problem was further complicated when I bought a new bog camera so I needed space and protection. I finally found a great bag that I plan to use on our next visit in August 2016 (my wife and my 20th anniversary).
I hope this will be my final purchase, but lets be honest I will probably find issues with it. It is light keeps my camera safe and I can switch it from the back to the front easily to keep my back from getting too hot. I got it on sale for $25 so its not expensive.
