With an annual show, each event will, generally, be a repeat of the previous one with a few tweaks around the edges. The long gap for MEX 2016 allowed a lot of changes to be made, not just the venue. While there were issues, particularly around the trade section being a long way from the exhibits and the limited signage, there was alot of positive feedback on the other changes.
The two-year gap may be frustrating, but it does mean that instead of applying sticking plaster solutions, we have the option to look at things in depth, talk to the trade, clubs, SMEE and individual exhibitors and visitors. This will let us make sure MEX 2018 is truly exceptional.
