Hey guys, I am planning a trip to Asia in the end of December.
My main places to visit will be DEL and KTM.
On the way out of KTM I will have a stopover left in my award ticket.
Based on the flights I can get I could stopover at BKK,MFM,HKG or TPE.
Plus I can make an under-24h stop in any of them.

The stopover will be 2 days at most, so nothing extensive. Which destination would you suggest for stopover vs >24h stop?

Thank you in advance!
Mostly interested in cultural/historical tour/overview.
