I'm with JDI19, I just don't think its worth the (likely)wait in the heat or the bother to get a "good seat". Plebes have their backs to you; no chance to influence that basic view of things by getting a "better seat". Invest your time on IDay finding a good shady spot to have a moment with your Plebe after the oath. I Feel Ya. That oath is a big deal, and I'm a guy who loves the view 20 rows up on the 50 yd line, but fact is there are no "great seats".
1) As long as we are talking seats get ahold of at least one folding chair for your Plebe to sit in when you get him/her back for those 30mins you will remember forever between oath and march in. If you are flying in, you can pick one up for $15 and just leave it behind, your Plebe will thank you.----Maybe not at that moment, maybe not ever,------------------------------------ but if they ever actually thought about it -----they'd thank you.
2) As long as you are talking pictures and viewing angles. The unforgettable moment for me as a parent was my daughter standing in formation waiting to walk into Bancroft. Picking up your picnic stuff can wait; grab the camera and hanky for this one; the looks your kid will shoot you from the ranks amazing. Hard to put into words, but its a mix of: Fear (holy sh* pht what have I done?); Gratitude (I just realized how cared for and protected I've been the last 18yrs); Sadness (I am moving on today without you at my side); Love (-----can't describe that one; but in my minds-eye I can see her face in that moment as I'm typing this).
Congrats.
