Will the diving be the same at both resorts?
No. Because of the difference in location between the two resorts, the diving itself will be radically different.
(n.b.- the diving on Roatan can be divided into a few different underwater zones, any one of which are chiefly only served by the local resort/dive-ops. The island is about 17 miles long. Although it is only 3 miles wide, this of course means that you are dealing with 34+ miles of shoreline. Hard enough to get around on by car- long range ventures by boat are simply not happening yet)
Coco View, an AI on the middle of the Southern Shore, does its diving on shallow vertical walls that run from 5' down to a 90' sand shelf. They are Sunlit all day long and thus lend themselves to being the home of many colorful macro creatures~ this may not be of interest to newer divers. There are two very shallow (45-65' deep) small wrecks there- and because of it's historical protection from heavy weather these wrecks have remained intact for many years~ thus encrusted in life and critters. CCV has boats and facilities that are pretty close to handicapped accessible. They offer an afternoon and morning 2 tank boat dive. They have a very easy access shore dive. (= great snorkeling)
Mayan Princess is an ala carte resort located toward the South end of the Western side. The diving that they feature is along an area that is protected by the RMS, so the newer diver will get a greater number of sightings of common bigger critters~ Lobsters, Barracuda, etc. It is, by comparison, deeper and darker than the South shore, it's big wrecks are comparatively new, but shredded by wind and wave even though they are deep at 100'+. MP offers a two tank morning boat and a single in the afternoon, usually 1 night dive per week.
Flights are booked, just need to figure out where to stay. I go with my father and he usually only dives twice a day. The only drawback to CCV is that we are stuck there. It appears that Mayan Princess has a beach (which we like to relax on when not diving) and we can go to other places to eat.
Your decision has likely already been made for you by your flight dates. Call and confirm if CCV even has any rooms available- the place books-up pretty solid. Might render this discussion moot and only valuable to future visitor who are in
ponder mode.
If beaches and optional dining is a deciding factor, your choice has also been pre-decided.
Go to Coco View for one thing and one thing only-
a dive vacation that allows
easy access to 5x a day diving, 24/7, 25+ dives in a week, end of story. [Think about this: Dad may have only historically dived 2x a day because diving was "work". At CCV, it's very low impact.]
If you want
a vacation with diving, Mayan Princess would be a much better choice. Beach access and not to hard to get to West Bay restaurants. Much more of a resort that almost any non-diver would like way better.
