...espec if it's something a bit unusual over there, like a Quinny. Lots of the exhibits at Sea World were stroller-free zones and the spaces to leave your stroller aren't secure. I would suggest either take a bicycle lock or leave yours at home and hire one at the park (although they might only be good for older children). I might sound a bit OTT but my Quinny Buzz drew almost as many admiring comments as my baby!
