my wife and I were able to catch the DewTour in Ocean City, MD earlier this year, so I can at least give you an idea on how they ran the first leg of this tour.
walk up entrance was free, you could pay additional money to get an access pass and have seating at the events, but we just walked up and watched the skateboard vert and bowl finals without any issue.
The events ran from about 11Am until about 8:30 - 9PM. It started on Thursday and lasted through Sunday. They had concerts on Friday and Saturday nights (Wiz Kalifa and some other rapper if I recall correctly).
Not sure if any of this really helps, but at least maybe it'll give you a little bit of an idea.
