Yeah, you are right. The only thing that I find it attractive (for me la) is the Agoda's 6% discount.
Gonna use it again for my Hanoi trip and probably Singapore trip next month.

Does the current EzyPay with 5X TreatsPoints (using Maybankard 2 Visa/MasterCard) gets creditted instantly upon posting of the transaction

The TP will also devided equally based on your ezypay months.

I suggest you call up CS and ask whether your parents are covered too. Depends on whether you are married or still single.

“Covered Persons” A person shall be a Covered Person under the Master Policy only if:-
1. He or she is:
a) The  Basic or  Supplementary Maybankard 2 Platinum Cardmember who is the holder of a valid  issued by Maybank in his or her name: or
b) The legally married Spouse or Dependent Child under the age of 23 of any eligible person described in (a) above; and

2. His or her Maybankard 2 Platinum Card Account is billed from Malaysia   

Good job.
For SCB, your parents are covered if you are still single 

For SCB,[SIZE=7] your parents are covered if you are still single
