Me, my husband and 13 yro daughter are planning to travel to Cartagena in March. Any reccos for upscale boutique hotels in the walled city w/ a pool and serves breakfast? How many days should we spend in Cartagena? Thinking of also doing Bogata or Medellin...which would you choose? Any must see/must do things in Cartagena? Reccos for nice warm Beaches?
