I think that S2 have found it's better value for money to run an "Event" every year or two, held over a weekend at a hotel, where they can showcase the latest CND products and techniques in a series of workshops - where attendees will gain a lot more product knowledge than if they'd gone to a stand at one of the shows for a few minutes... as well as it being a great opportunity for nail techs and other salon professionals to network and meet socially.
