I really enjoyed the visit to Harlem - the tour was very well organised, our guide and driver excellent and the choir amazing.
The meeting point is 690 8th Ave; there was a tour representative outside the door asking the visitors wait on the sidewalk for the coach to arrive - which it did at 9am. We visited the Apollo theatre, took a stroll around Harlem in the vicinity of 145th St and were then back on the coach to the church for the Gospel choir who sang for around an hour. Great singing, lots of hand clapping by the audience and a great experience.
