Stayed here for 3 nights while attending a trade show at the convention center. This JW is very nice and located right on the Grand river. Room was modern with a great view of the river. The bathroom was great with both a large soaking tub and a separate shower with a very cool double shower head.
It was a close walk to the convention center. You can walk either outside on the streets, on the sidewalk along the river, or if the weather is bad go via the "skytube" (skytube to the Conv Ctr is a little confusing as you have to go through the Amway hotel, it's kind of maze-like but warm).
Had a couple of very nice meals in the restaurant; Six One Six.
This JW also has a very nice fitness center.
Only thing I didn't like about the hotel was the use of annoying blue lights in the lobby area. On the couple of occasions we were having drinks I felt like they would give me a migraine if I stayed there too long.
