Hi Lis,

to the forum.
I dont have any knowledge about the TEFL course but perhaps someone else here can help.
Phuket is a photographers dream. Stunning land and seascapes confront you everywhere but the most interesting subject are the people. They can be very shy so be discrete or ask permission but they will provide you with some excellent shots.
Patong is indeed "crazy", too crazy for me these days but if you want plenty of nightlife, it is the place to be. I much prefer Kata beach to the south or Kamala to the north. Much nicer, more beuatiful and still plenty of great little bars and restaurants.
Hotels and eating options are so diverse and plentiful that it is difficult to randomly recommend something without knowing a little bit more about you and what you want, as well as your budget. Would you prefer just a comfortable bed in the best location or do you want "resort" facilities with all the trimmings and dont mind being a little further out. You can find it all but expect to pay big bucks as Feb is still high season. I would recommend looking at some of the properties on Agoda, work out what suits your budget and then list a few and we can give you an idea of what to expect from each of your choices.
Ask all the questions you want, there are many good people here who love Phuket and will be more than willing to help.
