I, family, and friends (7 total) spent the month of July on Ambergris Caye, in San Pedro Town. We rented an apartment not far from the High School. We swam, lounged, visited many resturants, street vendors, bars, and gift shops. Took the water taxi to Caye Caulker for a day there, again swam, ate, drank, and shopped. We all had a wonderful time, on both Islands. Our average age, 53. I raised the average because I was the oldest at 67. Every single day of our stay we were offered to purchase "weed". And of course scuba trips, real estate, and even "pretty ladies" by the locals we encountered along the beach, and in town. All we declined.
Had someone approched us with the offer of an FatTire Amber Ale, or a Blue Moon Belgian White Ale, I'll admit we would have not been able to resist, I personally would have forked over $40. BZD for a decent American Craft beer.
This is not an entirely a tounge in cheek comment, relaxing the laws on weed would go a long way in making Belize a more tourist friendly destination. But it wouldn't entice me (or anyone in my group )to return if it were decriminalized. We were, to a person, dissapointed in the beer available in Belize.
What would make Belize my favorite place on earth ? A thriving craft beer culture, relaxed weed laws, relaxed "gay" laws. None of my group are gay, a couple are "420". But all are beer "geeks". An open beer culture would skyrocket Belize to the tourist destination extraordinaire. Way more than relaxed weed laws. JMHO.

Life is short, don't waste it being unhappy.
