My son participated in the ODP program for 3 years for the 93 boys age group. It was a great experience since he had an opportunity to play with some of the best players in state from the top club teams in state: Rangers, Blue Valley, WSO, Magia, Fusion. He started program when he was going into his Freshman year in high school.
There are some very quality coaches in the ODP program and it was fun playing in the regional tournament.
I understand your frustration of more players not getting into program.It is good program if you can get the best players involved.
IMO it is not that the coaches and parents are not aware the ODP program is out there, but the combination of less overall talent in the program , cost - higher gas cost and additional time commitment in regular club events is what is leading to decline in quality players participating in ODP.
If you are looking for quality training and opportunity to have your daughter grow as a player suggestion is KU Residential soccer camp. There is KU soccer camp for the younger ages run by KU Women's coach. Attached is information.http://www.kuathletics.com/sports/w-soccer/spec-rel/070710aaa.html
