You could also see another of my favourite ex-Dreamland rides (The Schwarzkopf Zepellin) on the Jolly Boys Outing film.

Did you notice how the halfway house (between London and Margate) was the Roman Galley on the Thanet Way, and they drove up towards Cliftonville and back into Margate before visiting Dreamland? lol
Loudoun Castle is definately worth a visit - loads of the old rides from S.E. Kent are there. There's a Looping Star, Mary Rose, Troika, Enterprise, Heatwave, Bounty Ship (ex-Rotunda)... even that naff indoor "water" ride!
