Busy season - not so busy?

Was in Cabo this past Dec/early Jan. Had never been to Cabo during high season - previously went in May and August a few years ago. We were expecting it to be quite busy but were somewhat surprised by half empty restaurants and bars. Médano beach was crowded and lively due to the cruise ships but the rest of downtown area did not seem as busy. Was this an abnormality? In speaking with some of the bartenders and locals, last year and the year before were quite slow.
