The bobsledding is a ton of fun and the chairlift up (and back down) the mountain is lovely. The line ups are ridiculously long. We would have liked to ride the bobsled a second time, but that would have entailed another hour+ line. The people are really nice and the music is really loud, but it's definitely an experience worth doing.
This was a great excursion. But we had a lot of time left over and to add anything additional was very expensive, so I would suggest booking one more activity along with this. The bobsled was very fast and fun! Only wish you could ride more than once for the price. And the Sky explorer was peaceful and relaxing. Our only bad experience was after completing the excursion we got off the bus and went to a little shopping area near our cruise ship and the people there were pushy sales people and a random cab driver was trying to get my daughter, mother and I to go into a van in the back of a dirt parking lot to do hair braiding for a deal. It was too fishy and we refused to follow him, so we wound up at a hair braiding stand who charged incredibly too much should have done braiding before we went on the trip or found someone on the ship to do it. So my advice is to stay in the excursions areas and only shop there and do hair braiding anywhere else but with the locals.
