Hey, thank you for the replies.

One thing that I really want to know is whether it is possible to book flights/train tickets and hotels on short notices while i'm there, or will I have to book those htings in advance.

For example, if i take the train to Chiang Mai and want to fly out after i'm done, will I be able to get a ticket at the airport for a good price?

Same thing with accommodations, will I be able to get a room somewhere for a good price if I just walk in?

Thanks
