I need to go from Puerto Plata to Santo Domingo mid-week and return the following day (residency renewal). Any advice on whether Caribe Tours or Metro has the better buses, services, etc? Other advice for getting local transportation once I arrive in Santo Domingo is also welcome. I hope to arrive before 6 pm (still daylight) and just need a heads up on how to hire a taxi to my hotel near the Guzman offices. How much should it cost, for example, and if I need to worry about safety any more than usual. Thanks!
