Just a note - a number of folk have asked about joining in on other people's demos. In general, I can't ask someone who has requested a demo, to share their demo time with others. A demo is a customer's "special time" with the gear, a chance to hold the remote and do more or less whatever they please, without interruption.
Now, if friends want to arrange in advance to come as a group, that's absolutely fine - the more the merrier. And I absolutely encourage people interested in buying to bring spouses, as the RM/x is not a purchase to spring on the unsuspecting. They tend to... dominate the decor of a room.
So come one and all, individually or in pre-arranged groups as you like. Folk travelling over a weekend to hear an audition, can even borrow the guest room for the night (there are some decent little places around for breakfast). I can also recommend some area bed&breakfasts for the folk who are making it a part of their summer travels.
