I joined the coaster force US live in June 2012.
The short Trip report:
The itinerary was:
Day 1 (June 2nd) - Fly from Heathrow to Boston, and on to Lake Compounce and Quassy
Day 2 - Six flags New England
Day 3 - Coney Island & Rye Playland and new york sightseeing
Day 4 - Six flags Great Adventure
Day 5 - Dorney Park & Knoebels
Day 6 - Six flags America
Day 7 - Hershey Park
Day 8 - Kings Dominion
Day 9 - Busch Gardens Williamsburg
I also added a few extra days:
Day 10 - Kennywood (flying from Richmond to Pittsburgh)
Day 11 - Idlewild and overnight train to Sandusky
Day 12/13 - Cedar Point
Day 13 - Flight back, summing up and souvenirs
I didn't take as many pics as I'd have liked, as most of the parks were a bit too rushed to take the time, but the net should provide a good source of pictures for your enjoyment!
Days 1-6 were with about 15 others, mostly from the UK, but including 2 Swedes, a Canadian and a couple of Americans
Days 7-9 we were joined by about 10 more, mostly from the US
Days 10-13 were just me!
