"This is the actions sports industry’s superbowl of sorts, and with that comes the entire industry, and that industry is worldwide," said James Leitz, Senior Vice President of IMG, the company who owns the event..
The competition kicks off Saturday, followed by concerts and fashion shows.
All 157 rooms at the Shorebreak Hotel, popular with comeptitors, are booked for the week.
The 20 something crowd will open their wallets by sleeping, shopping and eating in surf city, said Marco Perry, the hotel's manager.

Elizabeth Burris knows she'll spend the week shuffling cars on her street, saving a spot, then moving again. Her concern is that the bars will fill up two blocks away on main street.

"If you walk by, you see the people are over-served already," she said. "And they're gonna spill out onto the streets, and they're gonna cause some problems."
