If you are a VMware Certified Professional you get a discount of EURO 200 on the three day pass for VMworld 2010. Normal price is EURO 1150. I believe during the registration for VMworld your discount should be shown. However, for my it was not. If your discount is not shown send an email mentioning your account for VMworld and your VCP number to VMworldEurope2010Registration@vmware-events.com and it should be fixed very soon!
