I used this on my recent Disney World trip. The pack is very lightweight, but sturdy. We're minimalists when it comes to taking things to the park, this had plenty of room for our needs and I carried things for our companions as well. The front cell phone pouch was perfect for quick, easy access to my phone. There was room for two cell phones, and we probably could have fit another. The bottle holders on the side hold a standard 16oz bottle. It was also small enough that we were allowed through security without extra search. The whole pack easily fit in the spaces provided on the rides. It was very simple to switch shoulders and resize for someone else to wear. I look forward to using this pack more in the future for hiking.The only con, and this is more personal, is that my back got pretty warm under the pack, but it was tolerable. (And to be fair, we were in the Florida heat.) The liner against my back and shoulder got sweaty, but washed easily.
