I really love Chase Field and I attended opening day this year with my wife and three month old. I've been to Chase Field many times before but it's my first time yelping it.
I was really impressed when I first arrived to the field the staff was friendly and even told me to go to guest services in section 128 on the main concourse, so my daughter could get a "my first D-Back game" certificate signed by Baxter the bobcat. I thought that was a nice souvenir.
Once we got into the game the facilities looked very clean and maintained, which was expected on opening day. Staff was helpful in getting me and my family to our seats. I don't think that there is a bad seat in the whole ballpark to include or seats, which were in section 318 (nose bleeds).
D-Back fans are pretty laid back much like me, so everyone was friendly and talkative. The two tickets I bought for the game were $48, but that included a voucher for two hotdogs and two sodas. Apparently this offer is available for every home game.
Inevitably my daughter needed to be changed mid game and I was pleasantly surprised to find that Chase Field offers family restrooms that were very clean.
The experience I had opening day was awesome and I would definitely be back for many years to come.
Go DBACKS!
