Playa Dorada is a bit busy right now so it is best to ring beforehand if possible. No-one will pay attention to the agreed tee-off time of course, but you will have done your bit by requesting one!!
At Playa Dorada, ask for Ignacio, Raymon (I'm sure that should be Ramon but he always pronounces it Raymon!!), Rafael or Raul. Tell them I sent you & to make sure the balls are bought at the end of the 1st hole - 10 pesos per (almost) new ball, RD $120 per 16!! You can then shank them all back into the water on the second tee!!! Give me a call if you need a partner - I try to get up there twice a week, normally playing 18 holes afternoons/evening. - Grahame.
