Always speak with your CCV DMs, but as in any and every dive op, everything is weather dependent.
CCV boats always schedule one trip to Calvin's Crack and other local East end sites, always one to Mary's Place.
If you haveta-wanna-gotta go back for a second look, ask if you might join another boat on a following day. In that it's your first trip, I recommend that you go for the ride and just follow the program.
You will be seeing the other 70 dive moorings not installed by the Roatan Marine Park. Buy their donation tag, they mean well.
Be sure to dive the Mr Bud if offered. Do every drop off dive, you always see something new...go slowly. People that decry the drop offs as "the same old dive" are just not getting it (yet). Learn the Front Yard and the Prince Albert Wreck.
Night dives? I suggest 8pm, your first one is on Sunday night, followed by at least 4 more, Monday thru Thursday! No ecpxcuses here, CCV is for 27+ dives a week. Go gettum.
