Hi, I've had a 18' foot pool before in the past before my fiancé and I met so she's not all that familiar with AGP as far as what it feels like when you have more than 2 people in it and what you can and cant do, she's use to the public size due to her swimming competitions. She wants the 24'(just to float around in when its just us) and I want the 27', the cost is not that much so that's not an issue, she's not trying to have people just want to come over to just be in the pool. I have some of my children here along with my siblings, she has her parents here and family visits(blue moon style)and I don't want to have a pool going, I wish it was the bigger one, I feel that 27' is enough and I need your opinions. Thank you in advance.
