Glad you had fun at the fair! We had an opportunity to go to the summer fair in Dusseldorf when we were there in July (no Olympia Looping but Alpina Bahn was there) and had every intention of going ........BUT after a soaking wet cold day at Movie Park Germany, a late arrival back to the hotel due to a detour for someone who got ill on the bus and urgently needed us to stop at a gas station, and the fact that the next day was an early start and a jam packed day at Phantasialand; we never made it. Knew we would regret it later but knew just as strongly at the time that all we wanted were hot showers and a warm bed, but that was our only real hiccup on the trip so won't dwell on it.
