We recently did a quick airport overnight at the Holiday Inn Sepang.
Marriott Titanium
Hilton Diamond
IHG Platinum
for context

I don't have a lot to complain about this hotel.

They are trying hard.

Booked base room.
Upgraded to Executive floor with lounge access. IHG Platinum - very nice.

Now, the Executive Lounge food offerings was mediocre. But it is Holiday Inn. I was surprised by the lounge.
During our stay there were five liquors, two reds and one white on offer. And some beer (sorry, no details). Three salad type dishes and four fried foods. Nothing that I could make a meal with.

The hotel area is really interesting. Plenty of opportunities to dine off-site in an industrial suburban area with a shopping mall. Hard to peg it. We liked it.

I would stay here again if we required an overnight stay.
Some noise in the hallways (earplugs required).
Excellent rain shower head.
