In my experience, Bangkok is a much more enjoyable place to return to than to arrive in.
It can be a bit of a shock to the system when you arrive fresh off the plane, for this reason I would recommend getting out of there quickly but giving yourself lots of time to explore it properly when you inevitably have to return.
After spending time in Thailand you will find Bangkok makes a lot more sense and becomes somewhere that you really want to explore.
Is this your business?
