A few years ago I found a clear-ish vinyl/heavy plastic backpack. It is fairly see through, so it is easy to see what is in it. I carry tons of stuff-a folding cup,Brita filter bottle, snacks, the digital camera(smallish Nikon 880 Cool-Pix),wipes, small vial of aspirn/anti acid/meds, napkins/kleenix,a few Shout spot wipes for clothe stain removal.Hummm- also a very small wallet, with passes, $$$, credit card!(s),cell phone, extra socks if I remember, and all the stuff everone might need. Having listed all that, it is NOT as much stuff as it looks like, honest! I take sample sized stuff, and the last trip I did not take any bag in at all. The family had to fend for them selfs, and weren't to happy or upset either way, but did miss all the "junk" I took in for all of us. Not sure what I will do this trip. I get to go down 3-4 days befor the rest of the family, and I want to spend the days doing different things I never get to do. So I will ditch most of the above, but will carry the camera, extra battery, and a small sketch book, with a few pencils/art stuff. Just to have a little different Disney day, I want to try sketching things.
