Guenmai and Bob, it seems almost impossible NOT to split the time in Bangkok unless you are traveling from a nearby country since that is where you are most likely to arrive and depart from. The hours of arrival and departure also tent to be odd.

We are spending 3 nights at the beginning and 2 at the end.

I think we will probably enjoy Bangkok but we are content with our decision to spend 5 nights during a 3 week trip. We will definitely post our thoughts on this when we return!

That would be "tend" to be odd, not "tent" to be odd! :-)

When I say that I wouldn't slit it, I mean that I wouldn't, for example, arrive and then stay two-three days and then take off and go somewhere else and then return for two-three days. I arrive Bangkok airport usually around 11:30PM...then sleep at a hotel in town...for about six hours(sometimes more)... and then leave early the same morning and fly down to Singapore and start my vacation there or wherever else I might be going and then at the END of the trip go back up to Bangkok and spend a large chunk of time there all at once....Or I fly from L.A. to Singapore and spend some days there and then fly up to Bnagkok and spend a chunk of undivided time there and then fly home to L.A. from Bangkok. I just feel it very disruptive and a waste of my time to split days up in Bangkok...as in getting all settled down for 2-3 days and then having to go...in all the traffic... back to the airport and fly somewhere else and then return and make the trek from the airport back to the hotel again to settle down for 2-3 more days. Nope, not for me. Although I'm one to change hotels in Bangkok and try different ones during my stay, I find that a lot less disruptive than having to deal with going to and from the airport twice. Happy Travels!
