We decided to take a chance on a $50 ($62 with taxes & fees) rate on hotwire, and ended up with the La Quinta. I'd let you know how it is, but I won't be able to tell you for about 10 months.
They have a continental breakfast included (which is great, since I prefer a somewhat light breakfast on the morning before the cruise), and also high-speed internet access. From Dave's site (see above) it is about 7 miles from the port, which is further than the 2 miles for the Raddison, but I can drive 5 miles to save that much money.
