Hi, I am going to visit London in September and I have a few questions if people don't mind so I can do my planning and not look like a total fool while on vacation. I have wanted to visit London for the longest time, I am going on an Adventures by Disney Trip to Scotland and on my way home I am stopping in London for a few Days. I have never been and while I know I could read travel books I would rather hear from the folks that actually live and work there and know first hand information. Let me preface this by saying I was born, raised, and work in NYC, where just about anything goes, however I know that is not true of the rest of the world an I like to be respectful of the places I visit. I will be arriving on Monday early afternoon, my flight lands at around 12:45 so after a taxi to the hotel I am estimating that I will only have 1 or 2 hours to do anything before finding a restaurant and having dinner. I also have tickets to the Ceremony of the Keys at the Tower of London that night. The other 2 nights I have show tickets and my biggest question is what is considered appropriate attire for the theater in London. In NYC you can get dressed to the nines or wear jeans it doesn't really matter. I then have 2 full days to see the City, with theater tickets each night and I would like to do the following The Changing of the Guard at Buckingham Palace Westminister Abbey The London Eye I must do High Tea somewhere and would really like a recommendation I want to go to Scotland Yard and Big Ben just to take a few pictures. i have looked at a private guide but I am not sure that is the best route to go, Opinons? I know there are so many other places to see recommendations would be great. Trains, Busses and Walking are fine modes of transportation but I would like to know if the trains run 24 hours or if they shut down at some point. Other recommendations for restaurants, casual simple food is great, I only eat shellfish so fish and chips I believe is out. I don't mind off the beaten path and I know that local residents will know the good places to go. I thank you in advance for any assistance you can provide and I am sure I will have more questions as the trip gets closer.
