CoCoChat is highly recommended.
I usually go for two weeks at a time. "Herself" just does one. So that extra week, I have a pretty set schedule for surface interval. Most times it doesn't mesh with others at the resort as they may be distracted by the evening rum punch or good conversation.
Me? I'm in the water doing a shore entry at 20:00, 22:00 and sometimes (but rarely) 02:00 hrs.
When my wife isn't there, it is mostly solo after the 8 p.m. dive. If you ask around, it's pretty easy to get a dive buddy for the 8 p.m. dip, but it gets tougher after 9 p.m.
In that the shore dive is so good and easily accessed, it is really not uncommon to see lights under the breakers of CCV wall at 1 a.m. and all through the night.
As far as allowing this or that practice, you are asked to advise the DM what you are planning and when. That's about the totality of restrictions. If you do not tell them in advance, you might well be restricted for a time~ so always speak up and "file a dive plan".
Other than that, you are treated like big kids and responsible for your own safety.
Pretty much so like it ought to be.
