Note... I beleive that the roomsavers coupons are only good, on a walk-in basis, subject to availability. No reservations???
If you go to the Radisson reservation site. ( I just look up Radisson at the Port ) it will show a few rates, but at the bottom of the screen you should click 'show all rates' to see if any cheaper rates are available.
I am not sure if there are any secret rate codes, like the FALL rate that I have heard about, that are not shown???? We booked the visit FL rate.
