No pool at Den Laman if that matters to you They are on Bari Reef - one of the better shore dives.
I've stayed in a classic superior at BelMar - they're as nice as they look. The Buddy shop is at the south end of their small parking area so it's convenient for tank exchange. Also Buddy's usually seems to have a boat there now. They give you a card so you can use the Buddy's drive thru also when diving north.
The ground floor classic superiors have covered patios - all the units have water views to the west as it's about 100' away. The only thing between you and it is the pool.
There is no food on-site, The two major markets in town are about a 10min. drive around the lagoon and past the airport -it might be Kaya Industria. Many of the better restaurants are near there also along the harborfront. The nearest purchased food - besides the Marriott's restaurant - is at the Plaza Resort or across from the entrance to it around the lagoon. You can walk over to Hotel Roomer for breakfast but they'll be surprised to see you.
Belnem is a quiet residential area with some smaller condo complexes mixed in. BelMar's house reef is a part of a site called Corporal Meiss - it's sort of flat for a while then drops into a rift where there may still be some huge purple tube sponges before dropping down around 100' like many of the nearby sites. It's good for the BMP dive but there's better nearby.
If you are going to dive south - the Hooker, Angel City, Invisibles, Salt Pier etc. are all within 5-10mins. drive. Since the property s 50' off the street - it's convenient to stop by - I left all my extra batteries etc. charging while we dove. Tank exchanges are easy - there's a gate at the street side end of the diveshop and your room key gets you into the public areas 24/7. Ground floor *Classic Superior units also have a wet closet outside the back door. And they have a night watchman who mostly helps you park - if full the lot is tight.
From CC you;d even have to drive down the hill to Oil Slick. CC is a good 10 mins. outside of town - even 5mins. from "dive resort row" (Harbour Village, Eden Beach, Den Laman, Sand Dollar Condos, Buddy Dive, Habitat etc.) It 's closer to Karpata, 1000 Steps etc. but each one is a drive to the next. At some of the south sites you see divers/trucks at the next 3-4 sites.
