I wore one on all my Disney trips as a child (in the 80's.)
I didn't wear one for the longest time in recent years. I honestly never really thought about wearing one. I normally just had a purse or a small backpack. But the purse put too much weight on just one shoulder. And the backpack just got annoying to take on and off for rides. And it made me all sweaty.
Finally...last year at Disneyland...I thought to myself..."why don't I have a fanny pack?" So I bought one and now I can't live without it on trips to disneyland and WDW. I even wear it when we go to the zoo.
I'm 26 years old...and married. So I don't really care if I look dorky or not.
Target now has "belt bags" for $10. They are basically fanny packs. But they have a few cute colors.
Here's a link to the green one.
