We were around the last row of the first section in short Right Field... just off the far dashers... and just outside the cover IIRC. Frankly I would have rather been in the upper levels to see above the glass distortion and more of the ice. I however wouldn't like to be too high... For the Alumni and Phantom Games we were behind Home Plate; great seats but I believe I would have liked being a section or so lower... maybe just off the rail... That said, they were much better than the lower level seats. I believe I went for the relatively higher cost on the extra games because they were not too expensive to begin with (all things considered).
At Fenway we were in the Right Field Bleachers and found them too far out and saw no ice... we watched the heads and had to look at their eye direction to know where the puck... We had small and far away video screens to watch the game with. The two Network camera stands obstructed some of our sightlines. I thought that being closer even though lower would offset the problems caused by the distance when buying the Bank seats... While much better, they were still not good for actually viewing the game... But the Bank Jumbotron was in good view and was a big plus.
Long story short... yeah the higher tier the better, but stay in the infield... and go lower rows in the tier's section. Expect to pay dearly however.
Have fun.
