Next week I'm going to London, UK, attenting a 2 day convention (it's an ERP solution). Full Price £150.--, 2 hot buffet lunch included. The price amount will be credited on my account wallet to spend on extras.
5 years ago, I went to another 2 day convention (document management company), in Berlin, DE, full price €120, with buffet lunch, and evening restaurant.
Prices have dropped quite a bit for me!
