Hi. My wife and I and another couple are going to Cartagena for three days in March. We all feel like we want a quiet getaway, so we're thinking about staying in this place in Manzanillo. It looks okay, but the beach looks only decent--the sand is brown and the water's not that blue. Does anyone have any advice about how to spend these three days? We want to clock some beach time, but would love to do it on a beautiful beach...Thanks!
