The 'wet' season or the off peak usually last until end of October. So now should be the transition period, nevertheless it is still a good time to go mainly because the crowd is lesser compare to the peak season and the accommodation will be relatively cheaper.
Band 1 is the nearest to the jetty, very quiet and serene place.
Band 2 is where all the restaurants/pubs, i think now theres even a mac donald will be located at. It is a lively place, much noiser but you can get access to all the fun within minutes away.
Band 3 was where i stay, just infront of the famous willy rock. Its slightly quieter, but i would say is the best place to stay and it is just around 10-15mins slow walk to band 2.
The boracay concept is, the front door is the main road, the backdoor is the beach. I had a walk from band 3 to band 1 for my massage and it took me around 40mins slow walk.
As for the activities, once step out of your resort onto the beach, there would be many people offering you their packages. Nego the prices to what you want, if not move on. I walk from band 1 to band 2 on my second morning, and i met more than 10 offers. In the end i negotiate the best offer for all my activities. Relatively cheap i must say. Its funny that they offer twice or thrice to the china chinese and they actually took it.
Enjoy your trip!
