We checked out 8 hours worth of places up and down the coast. These were our priorities:
1.Beach, rock and coral free great for swimming
2. Food Quality - rare cases of the common travelers diarreha at most places in mexico
3. Customer service - knowing that our guest would be well taken care of
4. Small - so that it felt lik ethe resort was "our party" if everyone was going to travel we wanted to see everyone. (unlike Moon palace which is like its own city)
Playacar Palace was all these things. When we had our site inspection there weren't many kids. The resort doesn't have all that much for kids to do, if i were a parent i would choose elsewhere.
I can't speak for everyone but spring breakers usually are on a budget. (approx $1500-$1800 pp including flight) is quite a bunch of money for a spring breaker, whereas for an adult... worth the quality of service you receive.
PLayacar is great too for all the free add ons. If you have 60 people coming you will basically have a free wedding and all free private events for up to 40 ppl.
I really liked the Royal but it was $$$$.
And I love Ibersostar, but its a 3 star so you take the risk of food, quality customer service. Iberostar Tucan was a perfect vacation but I would be nervous to have my wedding there.
Does this help?
