It should be great fun and great education for both of you.
Going to a convention, especially the first time, is like drinking through a fire hose. There’s a lot coming at you at once and you can’t possibly remember it all. What I do is take some notes during class, but immediately after class I write down the two or things from that class that I think are most important to remember, and which client(s) or group(s) it will help.
Then, at the end of the training, I think of the 2-3 things I’m going to add Monday morning, for the next month or two. If I do this planning, my classes change a lot. If I don’t do this planning, I don’t implement as much.
