I've got 4 buddy family members going to Thailand in the spring--the niece I went with last year, her hubby and my sister and her hubby. I fi can get them thru to BKK, you can get there! and they only have DL to use. Their target is Chaing Mai and assorted areas--I heartily recommend Kanchanaburi on the way. Please share your experience when you go, so I can offer some guidance.
Take a look at teakdoor.com--expat site (a bit on the vulgar side at times)
