Good bag for Disney?

Travel Info
We are going to Disney in Sept & we will be there from the 22-28. It is my boyfriend & I. We are planning on going to all 4 parks (MGM, Magc Kingdom, Epcot, and Animal Kingdom) + Universal. We are bringing a bag for the parks, we only want to bring one for both of us, & we will take turns carrying it. Can you recommend a bag? We need it to be sturdy, we both have slightly bad backs. In it we want to have 2 water bottles (small plastic spring water), lip balm, 1-2 ponchos, digital camera (small one), 2 extra AA batteries, our customized Disney maps/itenarary/list of phone numbers & dining reservations, travel size of sunscreen & 2 cell phones. One of us will have those small plastic waterproof card carriers around our neck for allour cards & cash, so the bag does not need to have a secure place for those items. We will be wearing a bathing suit, if needed, & we won't be changing. We will also wear sunglasses & a visor, but it would be nice to have room for them in the bag, just in case

Travel Tips

Wow your vacation sounds just like mine and my husbands. We take pretty much the same stuff and we use a backpack. One with lots of zipper pockets. It works great for everything. Also don't forget the ziplock type bags for water rides or if it rains. You don't want your cell phones or camera to get wet. You can also bring in your own snacks to the parks. We do it all the time when we go. You just don't want the bag to be to heavy as it does start to hurt your back more through out the day. And my husband and I both have bad backs also. Just so you know security does check your bags at the entrance but its a quick look through they don't take anything out they just want to make sure you aren't carrying any weapons or anything like that. Have fun. We leave the Monday after Thanksgiving for Disney World.

I wouldn't pack too much. But I would bring a little backpack that the little kids wear. This should do the trick.
go to walmart and get a beach bag there good size and sturdy they come in tons of colors
Really just about any bag will work since it doesn't need to be real heavy duty or anything. If you were going to carry a lot, then I would say to go for a nicer brand, something like Swiss, but I don't really think you would have to.

I always just use a backpack that has several different areas to throw things in. I will use one place for papers and things, and then another for anything like cell phones or MP3 player, etc. and then one for your water bottles and any food. Keeping things seperate will make it easier to find things and then always prevent your water from getting on papers and things like that.

I would stay away from anything that is too structured, if you will be riding a lot of rides you will probably have to shove it small spaces a lot, if it more flexible it is easier. Also, don't spend a ton of money on it unless you plan to use it again. I usually just get a new one each time I go because they take quite a beating in the parks.

Finally, just one suggestion. You said that only one of you would be carrying the money and cards and tickets. I would consider each of you carrying your own cards and keys as well as some money. In case one would get lost, you would not lose everything and it would make the situation not quite as bad. I would also put a little extra money in your bag and/or in your room just in case you would lose some and need some.

Hope this helps!

Have a great time!
Be there, done that! I would highly recommend a smaller backpack with padded straps, but one that isn't too "hot" - you don't want an extra reason to sweat if it is very warm. Outside pockets for sunscreen, a bottle of water, etc. is great. I always throw in a few ziploc bags of various sizes to hold cameras & cell phones, just in case it rains. We have used my elementary school-aged son's school backpack the past few times. This is a good size, because you can get everything you need into it without it being so packed you can't find anything. Disney conveniently sells backpacks at every gift shop:) Have a great trip!
I answered this question already but think a fanny pack type bag, while "uncool" is very convenient for Disney parkhopping.

If you get a disney themed one (posted a link of one up for auction to give you an idea of what I mean), you could probably share duty of using it with the kids :)
A sling bag like this one: (Jansport's are easy to carry and have a padded strap:ebags has several styles of sling bags but I was trying to find one that was not too girly.)
