A couple of suggestions that might help you get the information you're looking for:

1.) Browse FT's dedicated Thailand and Korea boards.

2.) Search for "layover" within each forum.

3.) Search for "layover BKK" site:flyertalk.com on Google. Repeat for ICN.

4.) If you still have questions post them in the appropriate forum, preferably including "BKK" or "ICN" in the thread title and giving only relevant itinerary details (approximate arrival and departure times).

5.) Give people some clues about what you enjoy doing and what you mean by "minimum spending".

Good luck!

Thank you IMH.
