DO NOT BOOK A TOUR - If I could give a negative star I would. I was on a Martha’s Vineyard tour today and had the worse experience. My son actually started looking to see if we could get an Uber. The tour guide talked about his private life the majority of the tour. I paid over $300 to hear about the Driver’s friend’s heart condition, his upcoming doctor appointment, how he traveled the world , how much he made when he sold his house, on and on for 3 hours. Very little about Martha’s Vineyard! We were also nervous with his driving ability and during one of his stories he mentioned he turned 75 in 2019. So he was pushing 80 years old. Irresponsible to let him conduct tours! Horrible horrible experience! And Viator wouldn’t even consider any kind of refund. Not sure I would book anything through Viator if they don’t stand behind the service they sell!
