all food free, maybe beer as well, depending on outlet....

wellness spa, massage extra charge...

ambank supp cards entitled entry....children below 3 usually admitted free...

Your spouse needs her own card or AmBank supplementary card.

For kids (rightfully above 3 years old) will require their own access too. It also depends on the staff as well, to be lenient or not...
For kids if required for admission, you may need to have a few principal cards to sign them in.

Nope. Like I mentioned earlier, if the staff allows free admission for your kids, then it is OK. If no, you will need to pay for them or use another two principal cards to sign them in.

In short, you will need 3 principal cards + 1 supp (spouse) = 4 for all of you. If the staff allows free admission for them, then only 1 principal + 1 supp (spouse) will be required.

However, the above is only for local Malaysia PPLs, for overseas PPLs they may not allow to have same principal card and sign for different people.

Sure can stay..by using the world card to pay..

there are 2 outlets that you can visit for free before going thru the immigration:

1. PPL @ Gateway (light food, buffet style + shower facility, 24 hours)
2. The Green Market (restaurant liked set menu, limited hours)

It is said that you can only use the same card once per day, with a valid boarding pass.

Green Market is a restaurant which anyone can go in, if with eligible cards then will have complementary meal. I think it opens until 10.00/11.00 p.m.?
Yes, before immigration.

KLIA has no PPL before immigration, there are PPL and Flight Club which are at satellite building.

One meal per card.

Recently AmBank has some restrictions, it could be just one PPL entrance with one card per day.
So if you have VI and WMC, just switch between two.

How many meals you want la?

Like I said, AmBank has recently restricted to one day one entry. So, your chances to get more than one meal in a day may not work. The staff may allow you to swipe but AmBank has the right to charge you.
Hence, if you have the VI card (since most AmBank cardholders will apply WMC and VI together) then you may use it for your second meal for the same day.
Green Market doesn't open 24H by the way: https://www.plaza-network.com/location_deta...=Kuala%20Lumpur

If the meals are split into two days, should be no issue.

You may refer to this TnC.

6. Cardholders are entitled to access the lounge only once per day. Any subsequent access on the same day and any access exceeding the 3 hour limit will be subject to the applicable charges set by Plaza Premium Lounge.

I'm not sure if it refers to the same lounge or different lounge. You may check with CS, recently only amended this clause.

Per entry per PPL per airport? Though same airport but different PPLs? As per you stated, it will be 4 swipes in a day (assuming if access all 3 PPLs & GM).

Yes, but don't expect fantastic good food. Just simple food, slightly better food is at GM.

Do you have it in writing, just in case being charged later ?

if you have it in writing, please share. will give them a call too tomorrow if i'm free.
i was told at the lounge ambank might charge it for the 2nd entry on the same day using the same card.
