1. The hotel's fitness center is fantastic -- huge with tons of equipment, high ceilings, views of the city, etc. The only bummer is that it closes (I prefer 24-hour hotel gyms) and that, unless you are a Hilton HHonors elite member, it costs money to use (I didn't have to pay thanks to my Hilton status, but I still find it obnoxious when a hotel charges people to use its gym).
