Sattahip is about 35kms from Pattaya and Jomtien so farangs never used to use the Queen Sirikit Hospital, well that seems to have changed now, a few years ago you would never see any farangs there, I went last week for some minor cosmetc surgery and the place was packed out with them, got to think it is the prices they charge.
About 10 years ago I had similar cosmetic surgery at the Bangkok Pattaya hospital, took them 10 minutes and cost a couple of thousand baht, last week at Queen Sirikit it was a bigger job, took longer and the whole lot came to 800baht, and yes, they do charge more for farangs.
For minor stuff I think this hospital is great, if you have something seriously wrong with you though I would give it a miss, one it is too far if your on deaths bed, and two I wouldn't entrust them with my life after watching them try to kill my girlfriend a few years ago, she had a punctured lung so her lungs were 3/4s full of fluid, they slowly drained them for 3 days then a new doctor decided to speed up the process and sped the draining process up, she complained several times that it was too strong, but heh, what does she know, then she started going into cardiac arrest, luckily they revived her, she was there in total about 6 days and the cost was less than 6,000baht, then again if they kill you the cost is pretty much irrelevant as you aint going to pay.
