Also consider Anthony's Key Resort instead of Cocoview.
Anthony's Key Resort - Roatan - Honduras
A. It's nicer
B. Some(most?) of the Key bungalows have their own private walkway to your own private deck. We went by them on an AKR boat - they looked decently spaced apart. Like waving/raise your voice distance if you felt like it.
C. The Dolphins are there.
For $125ish you can dive with them.
Dolphin Activities - Anthony's Key Resort - Roatan - Honduras Of course you can also drive over from Cocoview for that.
If I'm not mistaken, most of the overwater cabanas at Cocoview are doubles. So there's someone 20' away on their deck. It's popular so I assume there always would be. Whether that's good or bad depends on what you want.
One thing about Laguna Beach also "Each bungalow is set over the tranquil mangrove lagoon". It's very tranquil (read still) We stayed next door, our dive dock was on that side. Every afternoon around sunset the Sand Flies were pretty bad. Real shallow also - 4' deep. We bumped going in at low tide.
Most people go to Utila to snorkel with Whale Sharks during the spring months. I'm sure there's probably dolphins there but no one mentioned seeing any. Someone posted here once about snorkeling with wild dolphins from Cocoview once. I don't remember where/when.
Laguna's "Beach" is nicer than either of the others though. There's really none at Cocoview and Anthony's is small.
CCV has the best shore dive since they have the wall and the Prince Albert off the property. Anthony's is shallow and average. Laguna Beach's off the ocean side is a nice dive and you can get to two more named Utila sites if you swim west. If you want a pool, it's AKR or Laguna Beach.
One last Roatan option might be Barefoot Cay. It's a full AI resort, you would have your own private beachfront villa (not overwater) it's a much smaller resort than any of the above and they have their own dive operation on-site. Like Cocoview it's a private island. It's much more upscale than either (priced somewhat accordingly) but the food is excellent, the beach is very nice, you can
snorkel off the property behind the barrier reef and Mary's Place - one of the signature dives - is 5 mins. off their property.
Roatan Island Resort | Roatan Diving | Barefoot Cay It's a pretty small resort - about six villas plus a few shoreside lofts so I don't see how it could be too busy even if full. There's two smaller private bungalows available also - your own deck, private beach area etc.
