I am traveling to MV in late July. My mother, my niece and I haven rented a nice little house and are very excited about our 1st visit to the island! My mother is 70something and has slowed a bit in the past year. My question is whether it's best to take the bus to see the island or rent a car considering her walking and endurance has slowed. We are staying in Vineyard Haven but would like to explore other areas. If we ride the bus around, are the drop-offs close to things to do, restaurants? If we rent a car, how is the driving? Are there a lot of places to park when we stop in the different towns? Thank you for any and all advice!
