Gassed, when was your visit to Dunbar?
But...no bugs on The Rock, right? It's a minor point, but you'll get bitten on Roatan, no?
We were there in June of 2017. No bugs to speak of but they don't bother me much anyway. I will get a few bites on Roatan.
Everyone has differing goals. We have a nice home and cook great food so that's pretty low on our travel list. Water/life/reef and dive time are high priorities. I normally do 5 dives a day at Coco so Dunbar, lacking on shore diving and not much options on the island/rock, left me wanting.
We were also part of a private group that wanted to dive one boat. I think Dunbar could have used both of there boats and dove the same locations. As it was they had 20 of us on one boat. Stepping on gear getting on and off. No place to stand. The worst of it was with 20 people I would start my safety stop and it would be a solid 20 minutes before they were able to haul some of the old/weaker divers on board, make room for their gear and a small path for the next diver before the ladder would open up. It worked out to about 4 hours of drifting behind the boat over the week.
Opted for a night dive and that was great. Two of us and some critters I had not seen many of in Roatan (to clarify my earlier statement about small critters/same water) including a gaudy clown crab!
Other than that, dive quality, ease of diving and volume of diving makes CocoView really hard to beat.
