Was in Phuket back in 2016 -- we stayed at the Renaissance and like it quite a bit.

Back then Plat was highest and my award stay was upgraded to the pool villa suite which made for a nice 5 day stay with my now wife. No lounge but they did have a free alcoholic drink of the night every night at lobby bar and back then they offered 20% off F&B (and the F&B prices were pretty reasonable for a resort).

You could also walk or take a bike down to the little village that's closer to the JW and Marriott Vacation properties (though it was only good for buying a 6 pack of beer and diet coke for drinking in our pool).

Beach was nice (same stretch of beach as the JW, just down the road) and property was pretty empty (this was March) so it was a nice stay overall.

Haven't been back so can't comment on the other Marriott properties in Phuket
