Congratulations on your upcoming marriage. We've renewed our vows twice on Princess, and they know how to do things right. Check with Princess directly to make arrangements. I do not recommend getting married on any island unless you're f;ying there. If the ship has to do a detour or can't pull in for some reason, you're "up the creek". The Coral Princess has a beautiful wedding chapel, and you can see what it looks like on the Princess webcam website. It you're lucky, you might actually catch a wedding going on.
