We are planning a trip to Mexico in December and I'm very confused about where to stay. We'll be flying into Cancun and hiring a car then renting a villa or apartment. Most accommodation seems to be in Playa del Carmen but I'm wondering if it's too big a resort to be really relaxing? Quite fancy Akumel or Tulum. Has anyone been to any of these places? We want somewhere with a fab beach, nice restaurants and a bit of a buzz but not a huge resort with tons of bars, clubs etc either. Main occupations will be sunbathing and sightseeing! Thanks in advance..
