Carlos was the best guide!!! Itinerary was excellent..hotels ok except Cartagena hotel...very unsatisfactory..staff did not speak English...location terrible.. breakfast unappealing...day bus trip to Medellin very long and uncomfortable... We did enjoy the trip despite the above...PS we booked boat trip to Rosario islands through concierge at Cartagena hotel...Trip was terrible...Boat broke down twice...once going to islands and then again on return...very frightening as we had to transfer to new boat both times on water...we asked hotel to request refund and have emailed three times for a response...no answer... Thank you for asking for our opinion.
