Kathy,
Actually, I think it is a good decision not to rent a scooter! Last time we cruised to Bermuda--of the 6 couples we traveled with, two had accidents. Minor, but definitely scraped up. The bus seems so easy and you can always share a cab with another couple going the same place...I don't want to wreck a perfectly good vacation!!
Glad you are having a good time and thanks for the review!
