I went several years back when I still was a JW. I did not visit any halls or try and make any JW contacts though. I was on a tour of Europe and came accross the English Channel from Ostende, Belgium and landed near the White Cliffs of Dover. Went to London and stayed at the Tara Hotel accross from Hyde Park.
Went on a whirlwind Pub tour along the Tymes River and about got snockered. the Place fish and chips were excellent. Visited several of the tourist sites like Picadilly Circus, Westminister Abby, Buckingham Palace, etc., etc. and was happy to be in a country where people could at least understand what I was saying.
I got up on a soapbox in Hyde Park and tried to give my 5th student talk. Then I had to clean the tomatos off of me that people threw, ha.
I would like to go back and see if I could get Sarah Ferguson to arrange a meeting with me, so I could meet the Prince.
All and all, I liked the experience.
