New World Hotel Makati City, formerly known as Renaissance Makati City Hotel until last week, is already included in HK-based New World Hotels group.

In fact, I am currently staying this hotel (as Marriott Rewards Plat) until mid Nov, and have not yet been informed of such changes officially from the management.

Points earning, lounge access, etc. do matter, and need to be clarified (if it was in developed countries!?). Well, this is the Philippines, and I, though as an expat, am already accustomed to it, fortunately or unfortunately.
