Manila Marriott is a fantastic property. Spent last weekend there and the lounge was open both nights. Breakfast was free (for Plats) in the Market Cafe and had the largest variety I've ever seen before.
Free bus to/from the airport is only once per hour and took 40 minutes one way and 25 the other.
Casino adjacent to the property was filled with smoke so I could only tolerate it for 10 minutes before having to get out. Shakey's Pizza, Kenny Rogers Roasters and a coffee shop 5 minutes walk away.
Modern room layout that reminded me of the Bangkok Renaissance with the electric shade in the bathroom. Hotel is only 8 floors and you can hear some plane noise from the airport.
