This was GREAT for vacation. I went to Disney with 2 kids (one who was still using pull ups) and was able to fit everything we needed (plus my husbands glasses, hat and wallet on rides), yet it wasn't that big of a bag! It transfers from an over the shoulder bag to a backpack very easily, and that was a lifesaver for when my back or shoulders got sore. Absolutely love it, my travel go to bag for sure.
