I believe they are. We have upper box seats in the first row. The season ticket price is now around 23/ticket. I haven't looked up the single game price for those seats. My guess is they are around 27. I have been to Wrigley, Fenway, Petco, White Sox, Cleveland, Nationals, Seattle, and Pittsburgh, and they were all at least 35/ticket for comparable seats. And my Cleveland seat ended up being obstructed view and I moved.
There are Ollie bargain nights where tickets are 10 dollars. What other major sporting league has a 10 dollar ticket? Maybe the Wizards?
You can still sit in the front row at Camden Yards for around 50/ticket. In other stadiums, that seat will be at least 250 bucks.
So, go or don't go. But I don't mind paying the money for the best stadium in baseball.
