Looks pretty cool and like a fun time! For me, personally, thinking back to my early days of learning the guitar, I would have saved for the amp...but that's just me. Either one seems like a good investment, really. You have an opportunity to meet some accomplished musicians and will be hanging with others who share your interest in the guitar and music. It could be a really wonderful and inspirational experience that you take with you! Keep us posted if you decide to go!
