If you want to get some really good diving in se if one of the live aboards has space onthem for your time frame. Dollar for dollar the trip is usually less than shore diving and hotel/food. I’ve got nine days on a live aboard in march with a possible 30 dives for 2300. That’s 76 a dive including food and hotel. A lot of the sites are where the shore based people can’t get to and the sites are spectaclar and uncrowded.
