Thinking about what kind of bag to bring to the parks. We are going in the summer so I will need to bring water. Was thinking about a cross body bag so that I can hold it on the rides. Also wondering if my 10 year old boys should bring their own bags to carry water and other things. Would a string backpack work for them or would it get in the way of the rides. I also have 2 other younger children but no stroller so I would have to carry water for them too. Don't want to load myself down so that it is too heavy to be comfortable. What does everyone else do?
