Tie big bright patterned ribbons on each side. Not only will this help you spot the stroller when it is moved, but it will help others with the same stroller not to accidentally take yours, and vice versa. When DD was young, we had a stroller with an unusual bright colored, I later found out "limited edition" pattern. I had never seen another one like it anywhere. To our surprise at WDW we came out of an attraction at DHS and there was another one just like it parked almost right next to it. I almost grabbed the one that was not ours until I noticed it did not have ribbons on the handles. The CMs do move them a lot. I can't imagine how hard it could be to find yours if it was a common brand, very common color stroller- there could be 10 just like it around it! While there is some stroller theft at WDW, a lot of strollers that are taken or missing turn out to be the result of a stroller mix up- ribbons help keep that from happening.
