We were a little worried that such a touristy place would be cheesy and not worth it so we were surprised at how much we enjoyed it. It's a unique experience that you can only do in a handful of places in the world and it will be a highlight of your trip. I do have to disagree with everyone else recommending to do it on your way to the airport. We went immediately after landing and it was the perfect thing to get us over our jet lag. I'd definitely recommend doing it first thing rather than last.
