Been a season ticket holder for 20 years...can safely say that there is no comparison whatsoever...the new park is awesome! Sad to see Rosenblatt go but I'm all about TD Ameritrade now! I especially love being able to stand on the concourse and still watch the game. More legroom in the seats and built in cupholders sealed the deal for me. The tailgating is night and day difference too. It seems very calm in the TD Ameritrade parking lots comparred to the craziness at Rosenblatt. Probably because the tailgaters are spread over multiple lots versus all being crammed into one lot.
Atmosphere is way different too with all of the stuff in the downtown area surrounding the stadium...way more vendors, food, beer gardens, bars, restaurants, etc.
