Year end holiday?

So these past few days I've been thinking about going on a short trip. Maybe to Indonesia? Bali especially. Beautiful island as well as a nice place to relax and get away from busy cities and people. Or maybe I should go to Chiang Rai? Beautiful mountain resorts to relax. One of those would be perfect for me. I've actually considered New Zealand as well.. But oh well.. Decisions :) let me know where I should go this December! Somewhere besides the beaches. I want mountain resorts! :)
