Hi again. OK, I now have 12 days in Thailand and I still think I want to take the family to Angkor Wat for about 3 days. Howver, flying doesn't seem possible: my Star Alliance award ticket won't get me to Siam Reap (amazingly, Thai Airways doesn't fly there) and fares look pricey. There are 5 of us, so I'd need a very cheap fare to fly.

So I guess I'm looking at land options. Given my relatively tight schedule, I don't want to waste a day in each direction from BKK to get there (I don't want to spend 5 days on the Cambodia portion of my trip). Is there a time efficient and cost efficient way to do this?

Also, a "best of Thailand" trip seems to require a visit to both the north of Thailand and the southern beaches. Is there any way to more efficiently combine this with a visit to Angkor Wat or for practical (aka cost) reasons am I pretty much looking at Bangkok to Siam Reap back-and-forth, and then I can head elsewhere in Thailand?

Thanks for the help.

EDIT:

I found this rather comprehensive transport guide for BKK-Siam Reap on the seat61 website. It sure sounds like too much of a time waster to do this by land. I'll have to look at other air routes to Cambodia on Air Asia and such -- or just punt Angkor Wat from my itinerary.
