As another Colorodan, I would highly recommend a stay on the placencia peninsula. Although you will not be disappointed at all if you stay in AC the whole time, Placencia is fantastic IF you want a reallyslow paceand minimal nightlife. The Singing Sands Inn has wonderful grounds, cool tours, just enough to do locally that 3-5 days there would be great. I like to ge there first, get de-stressed, then head onto AC for a little craziness.
