I just discovered a very thorough Guide to the Bangkok Suvarnabhumi Airport. Yes, it does tell one how to pronounce the name and it's not a bad idea to practice saying it a bunch of times, as an American would never in a million years get the pronunciation right by looking at the word. I remember asking a woman on the staff of the airport to pronounce the name for me one time. She readily told me how to say it, but I didn't practice it enough, because I soon forgot it.
And it also tells what each level of the airport is for, which is pretty basic information. Just today I called my brother's hotel to ask them where he would catch the shuttle bus to the hotel upon his arrival. The answer was Level 2, between Gate #3 and #4. But we didn't know which level he'd be on when he arrived! If we had consulted this Guide, we would have known the answer to that one right away.
It occurs to me that it wouldn't be a bad idea to spend a good part of a day taking a tour of the public areas with this guide in hand. Hey, it's not essential, but it would be nice to increase one's familiarity with the place, especially if one is gonna use the airport a lot.
