Getting ready to purchase. I'm looking at either an 8'x8', no lounge or 7.2'x9' no lounge. When sitting in the spa I like the distance between people in the 8x8, definately doesn't feel tight, and in the 7.2x9 even more so (end to end at least). But I'm a bit concerned at the 7.2 foot end. Have sat in quite a few 7x7 and 8x8 but couldn't find a 7.2x9 to test. Anyone have any experience with these? or understand what I'm talking about? Greatly appreciate your opinions!
