What time? We dove with Coconut Tree Divers, they do 2 tanks in the AM and 1 tank at 1PM. If they have enough divers (usually) they'll do another around 2:30.
Coconut Tree Divers - PADI 5-Star IDC Dive Resort on Roatan, Honduras Good people - Gay [user]cocaloca[/user] and her husband PJ own it. There's an outdoor shower and a bathroom upstairs in the back to change clothes.
btw, "enough" meant 4 for us once. But my group was the majority of their business all week so that may have been a factor. If you get on the late boat ask them to dive Texas - it's a drift dive near West Bay. There may not be enough time for them to do it on the 1:00 dive.
They're in the heart of the West End - right where the road enters "town". It's also across the street from the taxi stand. During the day there were almost always cabs waiting. The non-divers will have a bunch of shops/restaurants/bars to browse while you're gone.
Reef Gliders is also right there on main street. They do 3 single dives at 9:30, 11:30 and 2:30. It's panga diving.
Roatan dive sites from West End Boats for either one are literally across the street - just off Half Moon Bay Beach.
