I would take the time to go to Nosara if I was on my honeymoon- it's kinda chic (by Costa Rican standards) and I would think most ladies would like it- romantic dinner at "la vida dolce" alone would be worth the drive
I did the very same thing on my honeymoon. We stayed at WRSC for a few days over New Years. We had a great time there and they threw a killer New Years luau. I surfed a little but it did not go over well with the wife. Good luck.
