Sorry, lying here in the dark unable to sleep, I typed a long page and it deleted itself as I hit send. Nice.... so to be blunter (sorry)
15,700 USD surgery. 20% down to secure surgery date. Prices rising by 10percent by october i think, write to sophie and check.
Hotel: 50 dollars a night. Do the full 20 nights; you'll have less chances of going home with complications (not that a lot of us do, but stilll)
Air tix from eu to bkk, via qatar air (the BEST airline in the world, trust me): 900 USD return
InternetL 100 usd for one month unlimited
extra bed at hospital: 15 per night for your partner or guest. THere is a curtain, but they WIIL see and hear things they may not want to.

Foood at hotel: room service 8 dollars per entree. Cheap options around the streets, but you will need at least two weeks to really enjoy that i'd think.
Laundry 20 bucks per load. Pricey i know
Everything else is included, from dilators, to bed pads, to pantie liners to paper towels, airport transport, internet at the clinic, alarm clock (seriously, for dilating), a heap of medicines and pain pills of course.... great great great how they take care of you.
Anyway, hope that helps!
