I don't plan to use airmiles. I intend to pay outright cash for my stay but it will be better if can claim 25% BRG from the Marriott published rate

Take for example Bali which always appear on Spontaneous Escape promo you'll need 14,700 KF miles 1 way to redeem

If you have Maybank VI, to accelerate you need have oversea spending of 14,700 x 1.4 = RM 20,580

If local spending you'll need to spend 14,700 x 3.5 = RM51,450

Double that for return ticket redemption

Europe destination, you have to spend into 6 figures

Why use such niche program?

Multi-cities doesn't work for Krisflyer redemption.
You need to redeem SIN - TPE under Star Alliance if you want to fly EVA air
If you just want to get to Japan then search SIN - HND direct

Where got transfer points between airlines one??

You use Enrich to redeem other airlines got la
