Find Your Cruise
Personally having a child wetting itself in terror as it zips 6 floors above my head is not my idea of fun........!
I like to board a ship where there are no queues for anything. That is, OK, impossible perhaps - so let's say no longer than 5 minutes queue on average for anything.
Just a thought is the Zip Wire classed as an extreme sport?, you know what the insurance companies are like nowdays if you do have a problem.
