The "vibe" on the beach--age, attitude, activities--changes nearly every week, sometimes in the middle of a week, depending who arrives and leaves. Age also changes--for instance a "family discount" in June brings more kids and infants, which we enjoy having on the beach. Main cruise ship periods--Christmas, Easter--bring a larger group of day-trippers. Bottom line--if you find a week that really works for you, try to keep that week, as many of the same people return at the same time each year. The same can be said for people you want to avoid. Certain weeks are more "party crowd." Personally, there are a few groups and couples we now avoid by careful selection of weeks. That worked well the last trip. However sometimes a week is affected by a moving holiday period like Easter. Major holidays--Halloween, Christmas, July 4--huge regular crowds show up. The odd thing about the beach our last trip--chairs near the Perch were so limited by beach erosion the Perch crowd moved to the other end. Lots of drinkers mixed in with the quiet readers. And the Perch had little business because everyone was doing shots on the beach from their own bottles. So, another example of how things change week to week, and group to group.
