If you are flying into FLL for a cruise out of Miami you will find many more "inexpensive" (compared to downtown Miami) hotel options near FLL. Use the link I provided above to start your search and then use a shared shuttle, like SAS or Go Airport, to get from your hotel or FLL to POM for about $15 per person. Same fare will get you back to FLL after your cruise, and SAS has a list of hotels that they pick up at posted on their web site - saving you a trip back to FLL just to catch the shuttle to POM. Uber or Lyft from FLL area hotels to POM should run about $50+ for the car - a good deal for 3-4 travelling together (as long as no one in the group packs like my wife!). If you need UberXL the fare will be about $75+, making the shuttle probably a better deal.
