I have taken many London Walks with the original London Walks company and have always thought they were really very good. on March 21, however I took their explorer day to Salisbury and Stonehenge and it was terrible. When we showed up for the walk it was mobbed. They did not limit it to a decent amount of people. there were 96! I think they had planned on about 45...one bus...but did not cut it off. They guide tried her best, but what can one person do with 96 people. They called in another guide from London who was there for the Stonehenge part of the day. Obviously a stand in..willing, but not able! Three busses of people...it was so unwieldily that we even missed our train to London, thereby eating up most of the evening.
A bad way to spend a day a day when on holiday. An expensive waste of time.
