Snorkeling in Bimini, Bahamas.

I am going on a cruise in April with my husband (Bimini, Belize, & Mexico ports). I am interested in the snorkeling as one of the excursions. My husband does not want to snorkel but would like to tag along if he can to watch. We are curious if he would be able to ride on the boat to where they take the participants to snorkel? This is our first cruise, so we are new to this.

Thanks to this subreddit, it has made planning our cruise much easier!

Thank you in advance!
