Tyrone, I've known many who have gone through the course, and I am continually impressed with the quality of the instruction that people receive. I strongly recommend it. It appears to provide a strong "base" of information, skill, and experience.
Those that provide the instruction are skilled, dedicated volunteers.

The modest cost is very cheap for the value of the course. I also find that people seem to make friends that they keep for years.

However, I personally find that the activities that Lynn describes are very different than the WTC, and the people are also different. My experience is that the WTC graduates are far more self reliant, and that those that go on the organized trips are a bit more towards the "take a tour" group, although there is crossover.
