Welcome to the Marriott Club.

A lot of specific answers will depend on what type of status you envision achieving with Marriott.

Overall, Marriott properties in Asia are pretty good, especially if you are Plat.

If you are able to amass significant number of points, take a look at redeeming for Travel Packages, which combine hotel stays award with Frequent Flier miles/points in one redemption. Probably the best value if you will stay at the same hotel for a week.
