It all depends what you want your kid wants out of camp. My daughter always attended two camps per summer. One was to get some serious skills and conditioning training and the other was to get some training but also have fun. The only camp she went to every year was Premier Soccer Camp by the Sea in Carlsbad held at the Army-Navy Academy. This was the fun camp since they would have beach time mixed in with the soccer training. I think the camp has changed its name to Ultimate Soccer Camps and now trains out of San Diego State U and Santa Cruz U., so I am not sure what the camp is like now.
She did attend the UCLA camp when she was 13 or 14 and did not like it due to the very large number of players attending. She did like the ODP residential camp in Ojai, but didn't like the ODP day camp held in San Diego (she said it was too easy).
