Lisa,
As for Dr. Agarie, I believe it could be even less than a month. Depends on their schedule. We booked 1 1/2 months out, our choice just so we could get air tickets, hotel, etc all set up.

I went to Mexico with DR. Kelly inTJ. His schedule is usually very open and can have you there within a week or two. He is very good and very hospitable I was very happy with everything and have not had any problems.
Good Luck
