I have the usual stuff in my owner's locker. Love the shoe organizer, but I use it over the bathroom door for all my makeup, hair items for me and my daughter, sunscreen, antacids, medicine, etc. I might buy a second shoe organizer for our shoes, I HATE tripping over my daughter's shoes in the middle of the night.
Things in my locker may change, we are now DVC members and will have more room for things. I might end up with two lockers after our next trip.
A couple things I have in there that others may not are, Cinderella's Pumpkin coach that I made for decorating in my window. It comes apart occassionally so I also have a glue gun and additional glue sticks to put it back together. And, it also takes up a LOT of space, another reason to get a second locker.
We normally visit once a year, but it has been more than a year since our last trip. Hopefully we will be living on the east coast again soon and will be able to visit more often.
Oh yeah, one other thing I have in there is adult beverages.
A must after a long day of walking around the parks.
