I will be at Brac Beach Resort end of March and will file a report on return. Last there in 2019 so anxious to get back. At that time the resort offered 3 boat dives per day plus 2 night dives weekly. It is certainly possible to shore dive but requires transportation to entry sites. If you have transportation it should be possible to boat dive AMs and then head out for 2 tank shore diving in the afternoons.
Personally, I find 3 tanks per day plus the night dives is enough for me there.
Afternoon dive boat does not get back in till about 3.30-4 so hard to squeeze in another tank after 3 relatively deep long dives. Even on nitrox, I find that my NDT is quite low by the end of the third dive with a profile of 100 feet, 60 feet 60 feet; 45 minutes, 60 minutes, 60 minutes. At Brac Reef Resort, if your computer goes into deco, you are out of the water for the next 24h.
LC Beach resort schedule much the same and shore diving again requires significant logistics.
The beauty of places like Brac Reef and LC Reef resorts is that you can arrive on day 1 and not have to lift a finger or think for a full week.
Some would call this lazy but I call it paradise.
