I would probably prefer the far east (Phuket or Thailand) personally, but I'm European so Europe is close by and not that exotic for me!

But - all I would say is - try to decide and book in the next day or two, if you book after the 14th January, due to the change in the award structure, the same hotel will cost you more points (although if it is booked up then you should be able to book on the 15th due to the more available inventory)
