AKR
is the huge all-inclusive resort...lol One thing to be aware of is I believe there's a single supplement.
What Chilly said...here's some general info about the West End you may find useful.
Roatán, West End | Scuba Diving | Roatan, Bay Islands, Honduras | PADI
Typically the resorts only dive their side. There are exceptions - the Dolphins are at AKR, the Shark Dive is at Waihuka off the airport. Just about every operator books either - sharks only thru an operator. We did both, our dive op (Coconut Tree) set it up for us. Quite a few shops also run around and dive Mary's Place but its' advanced. Some of the far West Bay dives are considered advanced also - they're drift dives. I didn't find any of them overly difficult though. And among the best dives - Texas is a good site.
Dives pretty much everywhere ar 10/$300 - they're often single tank boat dives and they usually return to shore between dives. Most operators do 3/day - a few 4/day. Night dives are $40 and some operator is diving just about every night except Friday/Saturday since that's the travel days on Roatan. All the AI's typically run Sat->Sat.
The majority of the restaurants in all price ranges are in the West End. Almost all the nightlife as well. There's everything there from hostels to pretty upscale accommodations - for Roatan. Most meals were under $20. Most lunches under $5. There's a couple small local markets in town and the local produce/vegetable trucks. Some days fresh fish also.
Some of the resorts are fronted by bars, dive shops, tourist shops or restaurants. Then there's others a little removed from the main street or out on the east point of Half Moon Bay. Those involve a short walk on a dark road at night. I probably wouldn't recommend that for a single female.
Sundowners Beach Bar is a good place to meet other divers. They're on Facebook. There's other bars along the West End as well - most waterview/waterfront. And in West Bay which is two miles farther west. It's not as active at night and the road between the two isn't safe to walk at night - fine during the day though. West Bay has the nicer beach - nicest public beach on Roatan. The cruise excursions know this also.
There's also a water taxi between the two locations till about 8PM. And cabs are pretty much always available - no one drives in the West End due to possible liability issues. The airport ride is $25 everything else is negotiable. As an example, Coxen Hole cost me $15 - French Harbor about $20 and AKR about 6. Cabs wait where the road enters the West End. You don't really want to go to Coxen Hole for much except maybe food shopping. And not at night. There's really nothing there once the cruise ships leave anyway. The bigger food stores are in French Harbor. Some very similar to what you find in the States. If you did want to ride over there to food shop - your cab will wait if asked.
If you are concerned about safety - all the AI resorts (Cocoview, Fantasy Island, Reef House or AKR have on-site gated security. They're all isolated by geography from everything else though. So to go out at night - besides sitting around the resort bar - would require a cab ride. From the south side AI resorts to the West End can be $40 or so - it's not often done.
There are two women in my group and they shared a cabin at Coconut Tree Cabins - neither mentioned feeling unsafe. Another decent option in town is Posada Arco Iris but since it's fronted by Argentinian Grille - a little louder till around 11PM - the Apt. decks look thru/over the restaurant.
Makes it a little safer also. If you contact a resort/hotel ask them what fronts it, there's a couple louder bars sort of nearer the west side of the West End - so it can be a little louder there at night. Sueno Del Mar might be another option also, it's sort of it's own compound, dive shop on-site and they have a small beach/bar waterfront. One of the few places in the West End that is - many of the others are across the main street from the water.
IDK how true it is but someone who lives/works there said Mame Tree is the only place that regularly gets burglarized. That was a few years ago also though.
