Just completed three days London/Paris. Much to fast but a nice taster. The Red Bus was easy and a great way to see the city but a little quick if you're taking pics. Took the Eurostar to Paris for the day. What a way to go!!!! Then do the Hop-a-Bus there, too. We had a marvelous day and can't wait to go back. Stayed at Park Lane which was wonderful and a great location for everything including witnessing the demonstations in Hyde Park. Also, the Marlborough Head Rest./Bar has great fish and chips and local atmosphere. A little further of a walk gets you the more famous Audley.
