We stayed at the Embassy Suites Hawk mentioned this past weekend. You could do like apparently half of the people who attended the game and park in their lot and ride the free shuttle. They supposedly check dashboards for parking passes, but I never saw it happen. I did see multiple people get off the shuttle after the game, get into their cars and drive away from the hotel.
Because of all the free-riders taking the shuttle, we used Uber to and from the game. Cheap ride, but it was hit or miss. Our first driver ended up having to back up the on ramp to 285 because she ended up in the wrong lane. She also ended up missing the big ass sign on Cobb Parkway that said RIDESHARING NEXT RIGHT and made the first turn towards the stadium, costing us precious time that could have been used touring the stadium or drinking free beer (see below). It's pretty sad when a guy who's never lived in Atlanta and who's only visited there probably 10-12 times in his life knows the way to the stadium better than a driver who is using a nav system. The pickup situation is not how the Braves or Uber originally described it either. The thing about going to the pickup area, receiving a 4-digit code, and taking the next available driver waiting in line? Yeah, that's bull****. Uber works the same there as it does anywhere else in the world. Still probably better than riding the shuttle back to the hotel though.
Regarding tickets, if you watch StubHub closely you can get some of the Delta Sky Club all-inclusive tickets for $80-$90 each if you wait until around 4:00 or so on the afternoon of the game. That's a pretty good deal considering you get a padded seat, in-seat wait service, a sit down meal (brisket and fried catfish when we were there), and oh by the way FREE BEER (well, not free, but you don't have to pay any extra for it once you've bought your ticket). Wine and well drinks are also included, but who drinks any of that at a baseball game?
