We are on our first trip to London and have 4 days (Tues-Fri) to see the city. Questions:
1) Are there certain attractions which can be grouped together and seen in the same day since they're close in distance?
2) What would be the best way to see the main tourist attractions? self-guided v. with tour
3) Which sites can we see from the outside and which should we have a tour guide?
4) We'd like to walk the city as much as possible. Which walking tour companies would you suggest?
Thanks for any help!
