Check out Kuki's article on the CruiseMates home page. It's titled "Kuki Gets Religion" or something similar. It is all about how to bid for a hotel room in Ft. Lauderdale on Priceline.
is a web site that lets you name your price for a hotel room or airline tickets. Kuki mentions another web site that gives you tips on how to use it. Basicly you enter the city, area of the city and the dates of your intended stay, the number of stars for hotel quality, number of guests and the price you are willing to pay. They accept or decline your price. The catch is, you don't know until they accept your offer exactly which hotel it will be, and they charge your credit card immediately.
For Ft. Lauderdale, it's really pretty easy. You will want to bid for a hotel in the Downtown Ft. Lauderdale area, not the beach or the airport. Start out at three stars and above for $70. That may get you Embassy Suites or the Marriot. Two and a half stars will get you Amerisuites. If your offer is declined, you wait 72 hours and bid again for $5 higher. It can take some time, so do it early.
We stayed at the Rennasiance, a 4 star hotel, for $100 last week by bidding on Priceline. It was a 1st class hotel at an incredible price. We walked across the parking lot to the Bimini Boat House restaurant for a very nice meal. Caught a taxi to the port the next morning at about 11:30 and we were on board by Noon.
Best of luck and enjoy your cruise!
