I agree with everything Juniper wrote, but I would like to make a plug for Las Galeras. LT does have great food, but we are a bit quieter and Playa Rincon can not be beat.
My husband and I have a small bed and breakfast in Las Galeras, in case you are interested.

And the flights via San Juan to Catey are being cancelled in September, so they are only option through the summer.
