My wife and I are very interested in going as well. We will arrive at LHR from MUC 9/19 in the late evening. On 9/20, is it possible to do a day trip to Salisbury, Bath, and WSM for Dismaland? We leave for AUH on 9/21 in the morning, so we would not mind being back in the late evening on 9/20. The most cost effective mode of transportation would seem to be http://nationalrail.co.uk, but I can't seem to get all itineraries set as one (ie. Paddington/Waterloo>Salisbury>WSM>Paddington/Waterloo. Must I book separately for each??? If I can put them all on one itinerary, will I be able to get a better deal? Is there a way to use points/miles for this? Please advise. Oh, and are there any other cheaper sites or are these set by the government? Any discount codes or ways of getting cheaper? I'm a sucker for saving money. :P
