21 dives anywhere sounds like a good thing to me. Do remember the good parts.
I dive when I can while traveling. I also frequently go to the NC coast without a previously designed buddy. I dislike group led dives. In fact I have done 7 total and we lost the guide on two of them. (The 3 in the Caymans almost did not count since the guide let us roam at our own pace over a wide area which was great.) What I do if I feel a buddy is needed or desirable, is I just hire a local DM. We discuss the dive and plan it jointly. That way we dive at my pace and they help me find cool stuff. Unless you are on a tight budget when you add up all the airfare, meals, etc etc it is not a major expense.
