As I ask with any such (U.S. & Caribbean) dive destination that seems to get a lot less attention (e.g.: discussion threads, trip reports) than others (I think Dominica gets more 'love' on the forum than Tobago; I see Dominican Republic mentioned much more often, and neither of those gets anywhere near the attention of Cozumel, Bonaire, Belize, etc...), what is keeping Tobago off most U.S. divers' radar? Why is it 'lesser known,' not used more often?
It's way south of here; what about round trip airfare?
What I'm asking is, while there may be substantial upsides to a Tobago trip, are there downsides?
Richard.
