I am looking to book a carnival cruise preferably to the Bahamas during December. I have taken two Carnival cruises before both during Spring Break and they are naturally awesome. I just wanted to know if I would be in line for a severe letdown, or if cruises during the winter months are somewhat on par as far as single good looking girls and an overall good time

As a rule, December is a slow month for cruise travel and you should find very reasonable fares. Almost all short cruises to the Bahamas are fun, but you may not find as many attractive single ladies on a winter cruise as you did during spring break. However, it's likely that there will be other singles on board.

Weather could be chilly too. Have done a few during the winter months to the Bahamas and spent time on deck wrapped in numerous towels. But you could get lucky and have it be sunny and warm. Just something to keep in mind.
