Snood,
It takes some courage to make plans for yourself. In my early days I started with small things and built up to larger things. If my A wanted to attend also, I made it clear that I wanted to go in separate vehicles so we could each arrive when we wanted, leave when we wanted and be responsible for ourselves. It was very interesting, but well worth it in the end. I found I had a better time, much less stressful and my A learned about making choices and experiencing the joys of his own consequences.
