Bring your favorite books, or the books you always wish to finish reading, because this is your fantastic opportunity to do so. You will meet rain and it pours; however, you can still go around in Phuget and Samui, enjoy the locals and good food. Canoeing isn't that bad, just don't go out too far from the shore. Krabi...hmmm... get good sleep when it's raining and then..errr..read some more books. I think you will like the locals though; they are very friendly and you might find some cool guides.
