I am having trouble deciding what size above ground pool to buy. I have actually put a down payment on a 24' pool but am now rethinking that decision. The next size bigger that the company I ordered the 24' from is a 30'. Is it worth the extra $'s for the 30'. I have 2 young children, both boys and love swimming so I know it will get a lot of use. Just don't want to make the wrong decision. Room is not an issue, just trying to justify spending another $1,000 for the pool itself.... Any advice would be greatly appreciated!! Thanks!!!
