There really isnt any shore diving except coco view, which is a great dive, but a dive which can also be done from elsewhere especially as you are 7 odd and can command the boat somewhat (negotiate with any dive shop). I would never suggest going to stay there or other resort (personal prefs) as there is not much action around that part of the island though (coco's) and I dont like that style of holiday.
How long are you going ? I would go to west bay, as much as I should plug some dive shop friends in west end, (where it is more interesting at night) but the two in fact are commutable ! And the beauty of west bay is unmissable, the island can be toured in a day easily from anywhere. Check some of the
links for places to stay here and here http://roatanet.com
How did you find the website by the way.
thanks
