Sounds like some folks here could use an Owners Locker!!! I love mine.....it has nice big towels in it, wine, shampoo/conditioner, all sorts of stuff that I regularly use at WDW!! It's so nice to not have to worry about all that stuff.
I do have shampoo/conditioner bars, from Basin, that I travel with...in my carryon just in case there's an issue. But, to bring towels, toilet paper and other stuff with me? Nope, not worth it to me.
