There are cheap seats . . .
I went to the new Yankee Stadium last month.
The upper deck seats are affordable and you won't get vertigo.
The Mohegan Sun bar = ripoff. You gotta pay to get in and you can't do it at the door. You must have a pre-purchased ticket to enter and it ain't cheap. The view out there from center field is cool but not really worth it.
And yes, the restrooms rock. Lots of them and very spacious.
Unfortunately, the Yanks went 0-2 at the games I attended.
