I agree with Watermom. What you have is what you are going to like, because in most cases you don't know any different!
I have an AG 27 Round and we love it of course. Lots of room for a few floaters (floating loungers)to be in at the same time and are not bumping into each other. I bought a badminton net and tied it up from one corner of the deck to the other and we can play easy 3 on 3 wide or even 4 on 4 no problems!
We also like the fact that we have 1/2 yard left for dog to run. We knew that what ever type of pool we were going to purchase, we were going to put decking all around it to give it the "feel" and "look" of an inground. We decided to go with the round and after building deck all around the round, we still have lots of yard left where as if we had an oval with the deck all away around, we wouldn't of had as much yard left.
No regrets here!
Good luck on your decision!
