I would recommend to stay at least 2 days in each of the major areas of PR. 2 days in Condado or Isla Verde (metro tourist area), Maybe also check out Dorado for 1 day, Fajardo area and the Viequez or Culebra Islands (2 or 3 days), Ponce for a day or 2, Rincon / Isabela / Cabo Rojo areas for 2-3 days. You will need a car for sure.
I would recommend checking AirBNB for each of those areas and just rent a few days in each area so you can see what is there and do not have to travel far each day.
Get with the members in the forum and have them take you around and show you what is life like in each of those areas.
You called yourself hippies, not sure if you are city hippies or down to nature types, if down to nature you may also want to check some of the towns in the center of the island or at least some of the locations 10-20 minutes from a beach for country/nature living.
