Great advice. I also have some advice... For the newbie heading to Jamaica...
When you arrive there is a great chance the first person you connect with has a garbage bag full of ganja on them, you will know this by the stench of fresh outdoor flowers. My advice is to NOT purchase any of it. Purchase ALL of it instead. Smoke on the way to negril, then roll many large bob marleys for the rest of your stay. MAKE SURE you scour for seeds. ALERT when you go out for dinner there is a GREAT chance a half of a large bob marley will be sitting in your ashtray, do indulge. Spread the LOVE and do share with friends, even make new friends and share with them. You will be amazed at how it brings people together- deep conversations about life, religion and everyday struggles will follow. BE prepared for how it relaxes your MIND, body and soul while you are on vacation.
