I stayed at the Hampton Inn for a 5 day conference (at the JW marriott), mostly because it was a good price and I am a hilton honors member. The hotel is pretty new and is clean, quiet and comfortable, so I was happy to stay here. It's also near the highway, so you can avoid some of the worse traffic spots in the area.
Unfortunately, the WIFI is excruciatingly slow, which makes it impossible to do work if you need to send / receive emails or use the web. It's enough of a problem that I might not stay here again.
