Well I will tell you my experience on the topics at hand:

1)You may and you may not want to skinny dip. Beaches on AC are not like most other places and the beach is more populated for travel than the roads. Again...most who go naked...SHOULD NOT.

2) My cart was stolen because I went into the hotel for about 15 mins to grab some beer, etc. ALWAYS use the lock. Luckily I got it back. Do NOT get an electric cart either. Try Amergris cart rentals, real nice and $50 for 24 hours.

3) Wait a day and ask your favorite bartender or bellhop. I got a nice "blunt" for like $5blz that lasted me all week. I was told that is the only way to get it...maybe from him? Anyway it was a while since I smoked a blunt and instead of taking a few hits, I took about 20. I was so whacked I locked myself out on the balcony. You have to be an idiot to import/export it, I find bellhops are the best source(even @ checkin), then your favorite bartender.
