Krabi is a very nice place and you surely can take lots of good pictures. Just hope that you get good sunny weather. Been there 3 times and once it was raining most of time I was there but when the sun is out and the water is crystal blue it is simply lovely.
Good food as well and nice Thai people.
After all the picture taking you need a massage and I recommend you to visit the massage hut No.4 run by 3 sisters.They are very nice and sincere ladies who can still remember me every time I visitand of course they give a very good massage. Just walk beyond the golden beach resort and you will hit the massage huts.
Enjou your trip!
