Are you parking overnight, or leaving your car when you go on a cruise? There might be some other hotels with Park & Cruise packages, though they might not be as nice as either of your original choices.
Haven't stayed at either one, but both have excellent reviews. We'll be staying at the Embassy Suites in January pre-cruise; we're flying in, so parking is a non-issue.
What I like about Embassy is its Happy Hour where you can mingle with others (many fellow cruisers most likely).
PS: In Norfolk, Va 2 years ago we stayed at a Residence Inn overnight, left our car in their lot with their permission, and saved $150 in parking fees, which more than paid for the hotel stay. If you could find a deal like that in FLL, that might be worth considering.
