I thoroughly enjoyed your Boston tour which was enhanced by Pam who goes the extra mile to make it enjoyable.  While I had looked forward to going to Plymouth, the tour to Salem was very interesting and the tour guide there was excellent.  Also, Ken is an excellent driver and made me feel comfortable and safe. As this was my 4th tour with Comfort Tours, I look forward to travelling to other destinations in the future.  I understand Philadelphia is contemplated and I would look forward to going there. One comment – it would convenient, if cup holders could be installed. Shirley Arnold more
