stroller lock?

Drill through the wheels with a 1/2" hole saw.

That would kill the sovereign life time warranty.

If you are worried, then just buy a cheap umbrella stroller for $14 to use at the parks. But honestly, strollers seldom get stolen at either Disney or Universal. I think it happens more at Disney because of the vast numbers of strollers there.
