I went to one with my two sisters last year. We had a fantastic time, saw so many neat ideas and projects, ate wonderful fattening food and promised to do it again this year. Unfortunately, weather and other commitments did not allow that to happen.
Have a great time. Do not push yourself to finish a project instead of joining in on demos and discussions. That was the mistake I made last year and afterwards, altho I was happy with what I had accomplished, I regretted not spending time visiting and learning and being inspired by others.
