I have the SX, and am in Canada, I have 2 teenagers, me and my wife, that's all we needed. I keep the 3rd row stowed, and have since I bought it. The configuration is a perfect fit for us. That being said, the second row seats move back and forth quite a bit and also move side to side when they are not all the way back so you do get a walkway between the seats if they are both shifted towards the outer doors. I'd suggest taking your seats to the dealership (leave the kids at home with Grandma if possible) and try it out. While it might not be a perfect fit for the few years they are in the seats, as they grow older those seats will become much more useful. Once they move to boosters and beyond, you'll be using the 2nd row with all the "gimmicky" (lol) features.
