I hate to tell you this but there is always a bigger better ship then the one your on or will be on. Kmart of ships .. no.. not by any means. Half of the adventure of being on a cruise is the company you will keep, the sights you will see. YOU will make or break your own experience. I saw the same show. While I'm adventurous, rock climbing, surfing etc.. just aren't my thing. I wouldn't use any of it. Enjoy your first cruise with an open mind then think about paying that extra $1000 for the bigger mega ship of your dreams... Its all good. Mostly what it comes down to is cost.
I hope you have a fantastic cruise.
