I apologize if this has already been suggested (I didn't read all of the replies just yet), but this is what worked for us. Last year we had just spent $350 on a baby jogger city mini and accessories so I was leery about leaving it after reading about stroller theft. So, we bought a run-of-the-mill bicycle chain/lock and we would thread it through the back wheels and around the bottom bar only. This way, the CMs could still move them as needed but it did have to be pushed on the front wheel only. DH asked a CM before doing this if it would be ok and they said as long as they could move it without having to carry it, it was fine. Of course, a thief still could have taken it but we were hoping our stroller would look like a less-easy target. It did take about an extra two minutes to put on/take off but DH had it down to a science and it was no big deal. As others have said, it doesn't happen constantly but I just didn't want to take the risk- not only would we have missed our stroller, but I knew it would have really put a damper on the fun. I hope you have a great trip!
