Personally, I will likely never take another Carnival cruise ever again after my first experience.
I would also avoid Carnival... (but then my husband calls me a "cruise snob"

). BUT there are other cruise lines out there.
On the other cruise lines we have generally found MORE activities to our taste than Disney, not less. Our October cruise on
Royal Caribbean's "Mariner of the Seas" has a minature golf course, a rock climbing wall, an inline skating track, an ice skating rink and many other things that Disney ships don't have.
On a shorter cruise (especially from Florida) on a non-Disney ship, you ARE likely to get more bachelorette/bachelor parties, more young adults, more people who want to play at the casino. Because of their value and access to gambling, these shorter cruises are often called "party boats". However we did one (4 day Mexican Riviera, from LA, Royal Caribbean) and didn't get that impression at all.... Maybe not as great as a 7 day cruise, but not bad...
It's horses for courses. If you have to eat (character meals in heavily Disney restaurants), sleep (Disney hotels only) and do (Disney theme parks/attractions/shops) Disney all the way... then stick with Disney cruises. If not, then it can't hurt to look at alternatives - bet you could have a 7 night cruise on Royal Caribbean's "Mariner of the Seas" for the same price as a 3/4 night
Disney cruise... doesn't mean it isn't as good quality, just a little different.
As previous poster has said, though, Carnival may not be the best alternative cruise line...
