I've contacted the reservation center, Hilton reservations, and a couple other places. Have been told there were vacancies for Sat but not Thurs and Fri, Thurs and Fri but not Sat, Fri and Sat but not Thurs, and any other combination you can think of. Just not Thurs, Fri, and Sat -- even at regular rates. The Vectric rate is out the window as of Sun nite. The Curtiss, another Hilton (a Double Tree), is about 1/10 mile away they say. One of the people I talked to said to call the hotel direct on Monday when someone with authority is in and plead my case. They must really have the reservations spread out between all the travel services.
