CFI,
AC is a perfect choice for a honeymoon, if you do choose to decide AC for your location. Mexico, and Cancun specifically, does not even come close to the serenity and friendliness you experience on AC. AC is much cleaner than Cancun as well!
Having travelled extensively around the globe, I find AC to be one of the most beautiful places I have ever visited. (I will be returning in a couple weeks!)
As most people have stated already on this board, AC has a simplified style of living. You may however experince more panhandling in Belize City. But, on AC, I didn't encounter any panhandling or begging. Even the merchants who ask you to buy their products respect your "personal space" once you say you're not interested. Trust me, AC doesn't even come close to vagrants in places such as NYC, Philadelphia, Dallas, San Fran, Boston, and/or Chi-town. Compared to those cities, speaking strictly based on homelessness, AC is the best place to go! Heck, AC is the best place to go regardless!
Anyway, do some research. From my standpoint, I would marry in AC AND have a honeymoon there!!!
Hope this helps ya a bit...
Cheers. JohnnyK.
