I will be sailing aboard the Norwegian Sun (sale date 2/16/08). Which Cozumel Shore Excursion should i book?

I know when my husband and I went on a cruise we went with another couple so we did our own tours. If I had to choose I would pick B) just because my husband and I have always wanted to do that. I think C) is quite pricey however as they say you can't take it with you so if you can afford it go for it, sounds like fun. Think of us while your sailing, back here in the cold.
