BPM in Januay, so you are too early for that. If you are there for New Year make sure you do the Flying Circus party in Tulum. One of the best parties I have ever been to.
When you are in PDC there should be parties advertised, if there are any in Tulum make sure you make the trip. The Blue Parrot was the best venue during BPM but not sure what will be on in December.
