We were there in early Apri on a weekday. LOTS more people. LOTS. Several groups, especially local teens. And almost all were textile! The few nudies on either far end had bushwackers (4) to deal with and they bothered the textiles a bunch too.
The first change we noticed was the road up the hill from the Grand Case gate had been cleared on the right side for about 5-700 cars. There's a clearing behind the beach that had been enlarged and a 25-30 foot Mayan statue head put up. A trailer Porto john structure was there but obviously waiting to be removed - not operating but nice to know they had one there for the music festival.
No other noteworthy changes. Beach was cleaner than I expected. No changes to "Danny's". Sand was good.
Overall, those who enjoyed the beach over the years might be disappointed by the "crowds" and bushwackers but as far as the festival itself, they cleaned up well.
Lots of festival and recent pics have been posted on another site, especially of the Mayan god figure.
