During my pre-op consultation with Dr. Suporn he explained the procedure and his technique to me, when I asked him whether I could "choose" from a range of looks for my result he told me that my result would depend on my anatomy and the amount of material he had to work with and that it was not possible to make it look exactly like on a given picture. Dr. Suporn seems to use as much of the available skin and tissue as possible, and if you definitely want any feature "smaller" than surgically possible, you should know for yourself in advance and be very precise about that when talking to him. Even then he may not be able to accommodate you, because of how the new parts are intertwined after the surgery. In my case, I just let him do his thing without interfering, and I really love what I have now.
You should familiarize yourself with all the details of the female anatomy "down there". Immediately after the surgery everything will be swollen, but after one week you will already see a great improvement. That will also be when you start dilating, and you should know which areas need special care. One particularly sensitive area is where your labia minora will be attached near the perineum, and although the doctor and the clinic staff will tell you to be extra careful there, you should actually be EXTRA EXTRA careful, because the stitches there come off much more easily than those in other places (called "skin separation"). Follow all instructions to the letter, like keeping your legs straight and together as much as possible, always using enough lubricant for dilation, not pulling the labia apart and so on.
Write down the instructions they give you (what to do, what not to do, when, how, ...) while you still can remember them. You will be given a booklet with written instructions, but what they tell you in person is much more detailed and sometimes different from what you find in the booklet.
Quit smoking NOW (if you do). Really.
When you check into the hospital the day before your surgery, ask for a proper mattress (the only MAJOR pain and discomfort I remember from my week in the hospital came from the %$#@! mattress).
Be prepared for quite some heat and humidity when going outside, plan your clothing accordingly. About one week after your surgery you will be able to walk between the hotel and the clinic, and although it is only a few steps, you will be tired and sweating afterwards. A few days later the doctor will allow you to walk more, and you will also feel stronger by then. The mall, the pharmacy, Swensen's, Pizza Company and so on can easily be reached by walking and will be popular destinations for you. (D**n, I miss the place... Have some icecream for me when you are there, will you?)
Don't be scared about going to Chonburi and having your surgery there, it will feel like home to you in no time, and you will be sad when you will have to leave.
There is probably much more, I will continue adding what comes to my mind.
Good luck, be safe, and enjoy every part of your transition as much as you can!
