TIS - Thanks for the information. My only fear is that the operators at the 800# may not have the latest, as that has happened to me in the past. If you try to book a room at Hilton Garden Inn from the Hilton website, although it says on the first page that they are 100% smokefree, the site will still allow you to book a smoking room. I've found that in major corporations, the right hand doesn't always know what the left is doing.
Btw, I checked the rates as well. The bounceback weekend rate is only $169. For $15 more, you get full buffet breakfast, which is certainly worth it.
