Cruise Ships as hotels

I just heard this on FOX... they might bring in cruise ships to act as floating hotels to help people. This is exactly what we did in Miami following Andrew.
A lady called in last night to the Larry King Live show and suggested this idea. I thought it was very creative. People are going to be homeless for months and I'm sure most of them can't pay for hotels that long. I heard an estimate of 1 million people left homeless. The aftermath of Katrina is staggering.
