You will enjoy the Island. She is truly a great ship.
Also, we have been to Caratgena several times. We have taken cabs and explored on our own each time. We have found the people friendly. If you get the chance then go to the walled city. The architecture is grand. They still use carts with donkeys. The city is no different than any other. Just be careful. Common sense goes a long way. You will have a great time.
You work hard therfore you should play hard, do not watch the world go by, jump in and participate
