Anything actually stolen-no. But we have lost a few things that haven't been recovered as well as one item disappearing from our room and never being recovered.
Dec. 2002. Day before we went home one of my DD beanies (her favorite one, of course) disappeared in the sheets. I contacted all L&F departments before we left and after we got home. They assured me "Fancy" would find her way home. She never did. Of course, she was "retired" and hard to find a replacement. But, lo and behold, while visiting Las Vegas at the end of Dec. my sister "found" Fancy there! We told my DD that Disney had sent it there by mistake (we were there too) and she still believes in the "Disney magic" On that same trip she lost a stuffed Pearl (from Nemo) on our first p.m. at Epcot. I also called all the lost and founds but Pearl was never located. That was the first time we lost anything at WDW.
Jan. 05-we lost my DD autograph book (with several years of signatures) getting off the train at Rafiki's Planet Watch. I noticed it right away but it was never found. I checked with L&F daily-even visited it a couple of times. I do hope the person who kept it enjoyed it, especially the ones wishing my DD a happy birthday!

Anyway, once again, more "Disney Magic" occured-several weeks after returning home we received a package in the mail from L&F-it wasn't our book but it was a new one completely filled out with every autograph you could imagine and then some. There was even a nice note from L&F saying they were sorry they didn't find ours, but here was a replacement. It was a very nice gesture!
That same trip I left my digital camera on the floor of our rental van when we returned it. I didn't notice til we got home. Even though I called (Alamo) as soon as I got home, it was too late, the van had already gone out for 2 weeks. I called back the day it was returned and, of course, my camera wasn't turned in. Again, I hope the person who found it enjoyed all my pictures.

All I really wanted back was the SD card. Luckily, I had taken both my digital and my SLR. I used my digital for mostly non-people shots so I still had the pix of my family. And I replaced that camera with a better one.
We do leave items in our stroller, but nothing off value. I take my bag and all my cameras on the rides. Nothing has ever disappeared from our stroller. However, I did have a scare one time after getting out of Mickey's Philharmagic. I couldn't find our stroller (not a rental). I finally located it over where the skyway used to be, missing the poncho that was covering it. I mentioned it to the CM there and she said she could replace it but we actually found it on another stroller (our name was on it). I learned that even if there are other strollers parked in an area not marked stroller parking-don't park there. Your stroller may be relocated!
Those two trips were the only time we had items missing, or lost. Not too bad figuring how many times we've gone.
I do write our name (and phone numbers) on anything that can be written on, just in case. Ponchos, disposable cameras, mister fans, etc. I also have now put my name and phone number on all my cameras (and camcorder), since I lost the one in 2003.
I have turned in items several times. The last time was at at CBR in Jan. 05. We found a watch at the playground. I wouldn't feel right keeping something I found because I know I would want someone to turn in anything I lost.
My mom did lose her cel phone a few years ago at
Disneyland and it was turned in. DL mailed it to her.
