Nick, I used to be a Season Ticket holder for the Peoria Rivermen (AHL Team for the Blues) and I woudl have to say it depends on what you want...

If you want to show your kids a lot of action, checks/cross-checking/boarding/hooking etc, and fights you are going to want to be about Section 103, 109, 113, or 121. I would say very bottom row if you are going in one of those sections or the top of the bottom section .. being in between the two will leave you looking at some tough angles through the glass. You have this problem with the lower seats as well to when there is action on the far end.
If you want an overall good view of every I would suggest 105, 106, 107, 116, 117, or 118 at the top of the lower bowl section. You will be able to see all the action without the glass blocking your views, only downside is if they get in a fight in your corner it can be tough to see..
I personally would never want ice level tickets behind the PB or the Benches... View can't be that great... although I haven't ever sat there... The season tickets i had would of been something like section 116 at the very first row walking into the lower bowl.. Puck knocked a guy out cold 3 seats away one game and paramedics had to rush him to the hospital... I didn't even see it happening as i was reaching down to grab my soda.. Point? At that level you need to be careful with the kids and make sure they wear hockey helmets and train them how to avoid the puck prior to game time
BTW, First row of the upper bowl in any of those sections gives you an excellent view as well... Then again I was sitting in a stadium with sellout crowds of about 13K so our lower bowl ws probably quite a bit smaller than your's...
I assume you have the youngsters in Hockey Camps already?
Which reminds me.. Denise Pemberton, lol ... My high school hockey team had a chick on it... Man were we shit poor !
