We plan to bring our McLaren stroller to MK -- first time travelling with a baby/stroller. If we want to ride on rides, we'd have to leave the stroller behind, and I recall seeing many familes do that. But does anyone ever lose their stroller due to theft? I hate thinking of criminal events at WDW, but I'm not naive enough to think bad things don't happen. So for those of you who bring your own favorite strollers -- I don't want to buy a cheap stroller just for this trip because I really like the McLaren and it is lightweight -- do you bring a bike lock or something? or do you just chance it?
