Just got back from this event. Arrived at 7pm, left at 9.30. This was my first attendance so made a mistake by not buying tickets. If I'd bought a ticket I'd get to the front of the stage and have a free meal. I didn't so was back watching one of the large TVs they had set up.
Have to say it was wall to wall people all along the beach. Amazing turnout. I have no idea who the bands were but they must be national since most people knew the tunes.
Temperature was bearable, lots of young things, nice atmosphere but we decided to leave just in case alcohol spoilt the experience. Our youngster was nodding off too.
Music was great. A Maori/Polynesian music slot was entertaining. Lots of food and drink stands and we were not ripped off like we would be in the UK. Bought a roll mat 100thb to sit on and parked the motorbike at Jomcharee. Cars not recommended at all. As we left, the queue was still stretched all the way to Petchkasem. Looked like one of the boats on the water caught fire.
There are 3 elevated VIP sections with good positions. If anyone knows how to get into one of those next year, I might try it.
IMO Worth the effort!
