I checked in at JW Marriott on Adams in Chicago today and received a nice note thanking me on my 15th stay ( I had not been keeping track), and crediting me 10,000 points. This is one of the things that keeps me coming back.

So what features/perks makes everyone else likely to come back to the same hotel? I know I love thermostats that let you control the fan, plenty of power outlets by the bed, free wifi, and decadent shower....
