(Speaking as a provider of services to affs and operators specialising in Europe, which might make me a bit biased!)
I am surprised to see that (previously) US facing affs who, lets face it, need to replace that Business, are reluctant to travel to Europe to meet with aff mans and service providers who can help them replace US business.
I attend most shows (CAC, GIGSE, EIG, IGCE, ICE etc) NOT because there is always a direct proveable ROI, but because it helps me understand the industry better (especially in the changing climate we are living in right now!) and also allows me to see LOTS of people in one small place.
Rather than saying its “$2000”, compare this to arranging 10 meetings with potential business partners at $200 each !
I have booked a NICE 4* hotel across from the Krasnapolsky (which i personally think is overpriced) for £130 per night (About $250).
