I went to the Cubs game on Sunday 4/4 (Easter) vs. the Pirates. Going into the stadium was very easy. No more "airport security"... Just scan your tickets and walk in (Unless you have a bag I guess). Sat in the upper deck, 327R. You can mobile order at your seats. I ordered around the 6th inning, but only had the option to pick up from the vendor. Okay, so went to the vendor, and there was a huge line, and only 1 cashier available to take care of the orders. I decided to come back closer to “last call” 7th inning. Came back in the 7th, and now there were 4-5 lines that were much smaller. Successfully got my food and beer. Your mobile order is not ready to go when you get to the vendor. They prepare it for you when you get there. I went to another game Wednesday 4/14… This time sat in the lower deck 212. Ordered hot dogs and beers to my seats through mobile this time. Didn’t show up for an hour. Went down to fan services who took down my order number for a refund. Apparently, it was a system (and systematic) issue, and many people were also having the problem. The staff was obviously very frustrated. Got a text that my refund had been issued. Went to the concessions in-person and got food and beer. About 20 minutes later, my food and beer that I ordered through mobile (to my seats) and already had gotten a refund issued for, was delivered. Just FYI, if anyone is going to the game, avoid ordering to your seats. Pick it up from the concession. And better yet, don't order until you see the lines at the concessions, and order to the vendor with the shortest ones. (Although, I'll admit, it was nice getting free food and beers after all the frustration, LOL)
