I have never been on a Shop Hop but there is one being advertised here through the LQS I use.

Having never been on one, what do you do on one? How do you go from shop to shop? Basically, any information you would share with me about them, what to do, are they worth it, are they fun, are you supposed to buy something in every store, protocol, etiquette, etc.

Thanks!
