Hi, I am sorry I didn't see this sooner. I have been to Haulover several times, and all of them were positive. I personally never noticed anything untoward. There was a great vibe, and everybody seemed to be relaxed and just enjoying the sun. (I have heard that at the northern end there can be a kind of cruisy vibe, but I personally didn't notice that, but wasn't in that area.)
The only problem I did have is that one time my car got broken into while I was on the beach. So I guess don't leave valuables in there.
I really enjoyed Haulover. I hope you do too.
Have a great time.
