A couple years ago, my son attended the Weil Academy summer camp. All I can say is, don't expect much. It is probably different if you are a full time student, which would mean that you are a pretty good player. I remember one day during the camp (Wednesday), they spent the entire morning playing soccer and other things over at a field near by, which really bugged me since I spent close to $500 for the camp to work on my sons game. The first day of the camp, Mark Weil had each and every kid stand, introduce themselves and say what they wanted to work on and get better at that week. My son said that he wanted to work on his serve. Well guess how much time they worked on serves other than during match play (which they do a ton of), ZERO. There was hardly any fed ball drills, which I would have expected more of. The week my son was there, the did a lot of court games such as king of the court.
My suggestion to you would be, if you aren't signing up for both weeks, sign up for the first week of the 2 week camp. When you arrive there, I would also suggest that you sign up for some privates (which we didn't do but wish we had) with Takeshi or Dimitar right from the beginning so that you get noticed and aren't lost amongst the other 60 kids. I found that the kids that were taking privates, got more attention than the kids who didn't.
Ojai is a great town and the club is awesome. My son enjoyed himself and made some friends, he just didn't get the tennis experience that we were looking for.
Here is a thread with pictures from my sons stay at camp;
My son just finished up the BYU tennis camp and I have to say, this camp was well worth it. They have a great daily progam which includes conditioning, drilling and lots of match play (singles and doubles). They don't take time away from the daily routine like the Weil camp did with playing soccer or frisbee for half a day. The first day they pretty much setup a round robin to see where you are at and then develop a ladder from that. The camp sets up four teams of 28 players (Navy, Blue, White and Tan) with pretty much equal amounts of male, female and ages. Each day the teams compete against each other and you are matched up based on your ability and where you are at on the ladder. The BYU camp also has a great end of day program as well (one activity is taking all of the players, both on campus and off campus, to the Seven Peaks water park). Lunch is included each day and if you are on campus, both breakfast and dinner as well.
Another great thing about this camp is on the last day, they take all of the players and setup 8 player singles tournaments. So, all of the #1 and #2 players are in a draw, #3 and #4 in a draw and so on down to #27 and #28. This camp has everything that my son and I were after, which was good instruction and hit a TON of balls.
