My husband and I (mid 50s and active) are planning a January visit. I was thinking of 3 nights near Arenal, 4 nights on the Pacific coast, with the last night near SanJose airport. We'll be renting a 4x4. I need some advice on where to spend our beach days. I've done research on the Domical and Santa Teresa/Mal Pais areas, and can't make up my mind on which area would be best. We don't like crowds - just need a few decent restaurant choices and nearby activities. We don't want to spend more that $150 a night for lodging.
