OK....Now Im back.
I got back from Ambergis last week and Im here to report, It was great.
Comparing AC to Roatan: As much as I loved Roatan, AC was more developed. There were certainly less of the euro-backpacker crowd and more Americans. the absence of the europeans has a tendency to take away from the feel of beinbg somewhere truly foreign.
If I was to go to AC again, I would definitely book a place just south of the cut. The really nice places to stay on AC are north of the cut like Journey's End (where we stayed) but are just too inconvenient to be taking water taxis into town every nite. However this still might be an option as the prices at the resort restaurants can get a little steep. Sixty bucks for a beach bbq buffet for two!?!?! Are you insane!?!?!?
The people on AC are very friendly and I would gladly go back.
