I don't have any personal experience with this place, but I was looking at the groupon travel page and there was a deal for a place about half way between LA and San Diego that was a 2 night stay for 4 people plus 4 hours of wake board or boogie board (don't remember which) rental for like $150 total. I'm but near my computer so I don't have details, but check out the website and see if it might work for you, it looked like a great deal!
