Being a parent myself, I overstand your father's concern. Worrying seems to be a parent's job. With that said, you are now an adult. You have been there before and your Dad has shown you around. If you are comfortable with going and use good judgement, I have no doubt you will be fine. I would give him your itinerary and keep in touch with him. I would also have a reputable driver that can transfer you from here to there with no worries. There are many on the board. Right off the top of my head, Kingsley comes to mind. I have known him for years and can attest to his honesty and reliability. Captain D's son Lynston is also a great guy. I'm sure you can send Captain a message and get all set up before you arrive.
Things can happen in small cites, big cities, the US and all other countries. Just remember to keep your mind clear and use good judgement.....always! Hope you guys work it out. Enjoy Negril!
