We went with a group of 7 other couples (16 of us) a week ago Sunday (March 9th), and there were thousands of folks on Haulover. We never made it back during the week, but I assume weekdays will be much slower, but even then, I would expect well over a hundred. Perhaps someone who frequents Haulover can chime in, but I was amazed at the number of people there. Luckily, the beach is big enough to accommodate the crowd, but "crowded" is still the best word to describe it that day.
