How many Hot tubs on Carnival Fantasy?

I was watching some you:confused:tube videos from Carnival Fantasy and I only noticed one Hot tub? Is there more than one, and also is there an Adults only one? The one I saw had kids in it and were splashing, I like hot tubs to relax in and not be splashed.. (sorry) Also any info on Carnival Fantasy would be greatly appreciated!!

4 total: 2 by the pool and 2 in the Serenity area (aft Deck 9).

One at the pool side is for kids and one is for Adults.... The 2 on the serenity deck is for adults only & I did see them chase anyone with kids under 18 off....

Thanks so much for your help!! :)
