My friends and I are headed to costa rica at the beginning of march. We are 30ish, female and were planning on going to tamarindo but I have heard how touristy it is and are rethinking that. I have heard how nice Montezuma is. Is this a better option? Or where else would you suggest? We are looking for a pretty beach, decent nightlife but don't want to see chain restaurants. Let me know what suggestions you might have.
