We did Clonlara last year. TBH, I wasn't very impressed. The correspondance was not good. A friend of mine did it too and when she went to get her ds's transcripts and meet with her teacher, the teacher didn't show up, twice! I chose it b/c it was close to us, only a half hour away, and I thought we would do the activities. They didn't really make anything easy. I think the main problem was that they have an on campus school as well and pretty much put all of their time into that.
I hope I haven't misrepresented. That was just my experience. We aren't going with anyone this year.
