Isnt that something your club director should be figuring out? Might be time to re-evaluate especially if you are looking for more competitive play.? The other issue is some of the larger well known tournys book very quickly so you may find yourself shut out.
Why don't you look at some of the larger established clubs as they typically will say what tournys they will be attending.
I would also agree with the previous poster that you will not find competitive play at the LI tournys.
