18' AG Advice

[cramar]

Hi, first post, great forums.

Putting everything together this winter for an AG pool purchase and install in spring 2011.
We have a large yard but the desired location for pool/deck leaves us limited options, I know an 18' round pool will fit but nothing larger unless we go oval.
I spray painted an 18' round on the grass and all initial reactions were that it appeared a bit small, although I'm not sure if a line on the grass accurately conveys magnitude of the pool.
The wife is pushing for an oval (+- 15 X 24), which I'm contemplating but now the price jumps drastically in that I planned to install the 18' round myself, no way I'm doing an oval.

Just wondering if anyone has opinions on an 18' round and how it is for room/enjoyment. I'm really hoping someone could share some photos of people using an 18', just to get some context of people and available room. I've searched everywhere for photos and there just isn't any.

Any help is greatly appreciated.
