First, ChangeDetection.com (see earlier post) did work and I received an email notification within minutes of the website changing this afternoon that annouced the FSA conference room block was open.
Downside, it was probably too early, since currently the online reservsation system is not accepting the access code. Some forget to flip the switch? Instead I called the reservation number and was able to book my room.
The room block opening will probably be in NASFAA News on Monday morning, so you probably have the weekend to book your room at the main conference hotel.
