I was over in San Francisco recently and the whole experience at the baseball game we took in was simply superb. Night and day to here.
Tickets alone it was so easy...bought online, downloaded the MLB app, linked up the ticket to show a barcode and it got scanned at the door by a friendly steward. No queue tonget ticket, no paper, no need for a big turnstile and squeezing in, no queues of any note as there were loads of stewards with scanners and in in less than a couple of mins. That included being searched too. You could also actually change your seat right up to you went in.
