Pre-registrations for the next Opti-München fair, which will be held on Jan. 28-30 in Munich, are running 35 percent ahead of a year ago. Especially visitors from the northern and eastern parts of Germany and from other European countries are booking tickets in greater quantities than in the past, and many are taking advantage of special travel and hotel packages. Pre-registration is possible under the website until Jan. 7. Opti München says it has already received stand commitments from more than 600 exhibitors representing 900 firms from 45 countries for the show, which will be held at Munich's new fairgrounds. Meanwhile the Cologne Fair, which organized the now defunct Optika show, has been sounding out potential exhibitors about their interest in new trade shows in Asia or Eastern Europe.
