I had no problems in the winter months. Wx was pretty good and was able to fly 2-3 times a day. From what I hear they are getting short on instructors now, especially with the airlines hiring the way they are. Usually my checkrides were scheduled a few days in advance, didn't have to wait long at all. Most stagechecks were scheduled a day or two in advance. I still flew up to the day of the checkrides and all.

My guess is that the summer months would have the highest amount of students due to schools being out, however I don't know what it's like down there now. It may not take you 5-6 months if you get there in the winter...if your really proactive.
