I am buying a DONE3 ticket. For my four Asia segment I was going to fly:

HKG-KTM
KTM-HKG
HKG-CMB
CMB-KTM

I am now thinking that CMB may not be a feasible destination. I had originally included CMB so I could visit the Maldives. I have never been to Sri Lanka or the Maldives. After reading/researching about the destination, I realize that I need about 14 days to sightsee in both places. I hadn't planned on staying so long in these two places, especially since I have a month of on the go travel before I arrive in HKG. After a few days in HKG, I will travel to KTM. I only plan on being in KTM for 5 days.

I have been to most OW destinations in Asia. I am looking at the list of OW destinations I haven't been to in Asia that I can visit [instead of CMB]. The flight needs to be from HKG, and I must return to HKG and spend some time there before I travel on my transpacific flight (I am travelling eastbound) from HKG.

Of the destinations I haven't been to, my destination choices are:-

Karachi, Pakistan
Kota Kinabalu, Malaysia
Dakkar, Bangadesh
Banaglore, India
Jakarta, Indonesia
Dili, East Timor

I have never been to Pakistan and given the event in the news recently, I will avoid this destination. In Malaysia I have been to Penisular Malaysia and travelled around the region. I have never been to Bangladesh and this of little appeal. I don't care to visit India, I have travelled around the country and Bangalore is of little appeal. Also, I would like to avoid obtaining a visa in advance and a visit to India would require this. In Indonesia I have been to Bali. I have never been to East Timor

What should I do if I change CMB? Which destination, Columbo, Kota Kinabalu, Dakkar, Jakarta, Dili is an expensive destination to travel to?

I know I will get more miles by travelling to Columbo, so that was part of the appeal and the reason why I choose the destination.

What to Flyer Talk member do in this situation, a MR? Visit an off the beaten track destination?

Any advice from flyer talk members who have been to any of these places will be appreciated.

Thanks.
