My husband and I were certified in November. Since then, we've done Bonaire, Cozumel, some North FL rivers and springs, and we have a trip coming up to Key Largo.
We want to book a trip for March of 2020 and can't decide where to go. A travel agent at Caradonna Adventures has recommended Ambergris Caye (Ramon's), Roatan (Anthony's Key), or Grand Cayman (Cobalt Coast). It will be just the two of us and no kids.
I want awesome, easy diving, and a resort with pretty views and great food for when we aren't diving. Reviews about the awful sand fleas and mosquitoes have me hesitant about Roatan. I've read the diving in Belize isn't as good as the other locations. And Grand Cayman looks so manicured/upscale, and I think I'd prefer a more laid back vibe. But if the diving is superior and it has the great food, then it would probably win.
Opinions or other suggestions?
You don't mention budget, but if you can delay your trip to later in April (after Easter and Spring Break) things are often cheaper and less crowded in many areas of the Caribbean and the water is warmer.
We've gone diving on both Ambergris Caye and Roatan and we had great trips, and the biting insects were bad, but I thought that they were even worse on Ambergris Caye than on Roatan. A lot depends on the winds, if there is a good breeze you are less likely to get bites. When the wind drops you are a target, and at night the bugs get worse, but you must already know that from living in Georgia.
In my opinion, there is a hidden cost to visiting Roatan and some other cheaper areas of Central America, Mexico, and the Caribbean and that is the risk of contracting tropical diseases. For our trips to Roatan we were vaccinated for Hepatitis A and B and Typhoid, and we took anti-malaria medication before, during, and after the trip. We also used the DEET bug spray to try and protect again Dengue and Chikungunya, and we were careful about the food and water we consumed. That adds to the expense of a cheap dive vacation and it detracts from the fun! Again, it's my opinion.
One of the things we like about the Caymans is that we don't have to worry about eating the food or drinking the water or need to take extra precautions against tropical infections. It can be an expensive destination but it should be pretty easy to get there from Atlanta. You can also get bad bug bites in Cayman, but they do a pretty good job of controlling the insect populations, especially on Grand Cayman.
If you are looking for a dedicated dive resort on Grand Cayman then look at Cobalt Coast, Sunset House, Lighthouse Point, and Compass Point. Sunset House is closer to George Town (about a mile south of town) and not very far from Seven Mile Beach, Lighthouse Point is north of 7MB but not far, Cobalt Coast is in a more remote area a bit further north of 7MB, but an easy drive to the more popular tourist areas. Compass Point is on the East End of the island, and it is a longer drive (45 min to an hour) to the airport and the more popular areas.
Sunset House, Cobalt Coast, and Lighthouse Point have onsite shore dives on the house reef that can extend your diving opportunities. Sunset House mostly dives the West Side and South Sides, nice diving and usually pretty calm but not generally considered the best diving on the island - but lots of fish life. Lighthouse Point and Cobalt Coast usually dive the dramatic North Wall (weather permitting) or the West Side, and Compass Point dives the beautiful East Wall but they will head around the corners to the north or south sides depending on the weather.
There are also inexpensive shore dives available on the island at places like Turtle Reef/Macabuca (north of 7MB) with onsite dive ops and facilities.
You can also rent a condo, prepare some of your own meals, enjoy the many restaurants, and go diving with one of the many fine dive ops available, especially in the 7MB area. It's a good idea to have some kind of diving package and/or kitchen facilities or meal plan, because eating out 3 times a day (and buying boat dives al la carte) can get pricey.
If you want to get off the beaten path, take a look at the dive resorts on the Sister Islands of Little Cayman or Cayman Brac, they are only a 30 minute flight from Grand Cayman (similar to flying to Ambergris Caye from Belize City). They are small, remote, are rural areas but still with a high standard of living. We usually stay at the all-inclusive Cayman Brac Beach Resort or Little Cayman Beach Resort (sister resorts to Cobalt Coast) but there are also other options available on the Sister Islands.
Since you are new divers living in Atlanta, it is likely that you will eventually visit many dive destinations in the Caribbean, Florida, the Bahamas, and Central America - if you continue to enjoy diving - so take a look at the options and find the best deal for a nice place that looks good to you. There are differing opinions, and pros and cons for every dive destination.
You might also want to consider a liveaboard vacation because you can do a lot of easy diving in a short period of time, and also look at other "new-to-you" dive destinations like Curacao, St. Croix, Saba, and more. Good luck!
