This is completely up to you. Most campers and instructors bring acoustic-style jazz guitars.
Extra guitar strings, a small portable music stand, pencils, a recording device should you like to record a class.
No. If you would like to bring a small amp, you may. Amps are not necessary unless you bring the type of guitar that requires one to be heard.
No. All classes will be in the hotel. Once you arrive at the hotel, it is not necessary to leave. If you would like to explore the area and/or go out to dinner, or if you have a guest, you might prefer to have a rental car.
Registration is limited to the amount of campers Frank and Vinny feel will benefit from attending.
