I live in Indy and am happy to answer any questions you have. Looking forward to seeing Bama gear all over my city for the next week! Here's a few tips that will hopefully help:
Weather: It's going to be COLD! Highs Monday will be mid-20's with windchills in the teens. The stadium is domed, so the game will be nice and warm. But come prepared if you'll be walking around downtown or tailgating. It's not going to feel like a championship game in New Orleans or Miami.
Parking: There's a few options. You can check Stubhub or other 3rd party marketplaces for parking passes, but I wouldn't worry about it. There's not a ton of actual stadium parking because there's a ton of normal parking downtown around the stadium. If you get close to the stadium, expect to pay $40-50 for private lots. My go to center:
Circle Center Mall (parking at the Georgia St or Illinois St entrance). They don't jack their rates for events and it's a reasonable walk to the stadium. They have an underground 2 level garage and a 5 story parking garage across the street. It can take a while to get out, but it's the most reasonable close parking I've ever found.
Regions Tower - This is your cheap option, but not convenient option. It's an office building with public parking far enough away from downtown that they don't raise their rates. It's usually $5-10 to park, then about a 5 minute uber to the game. Other benefit here is this is next to Mass Ave, which is a big strip of bars/restaurants. (More to come on that) So you can park there before the game, hit up some cool spots, then quick uber/lyft to the game.
Private Lots - If you drive around or look on a map, you might be able to find some private lots selling public parking. These are usually the closest to the stadium, but the priciest options. For an event like this, I'd expect minimum $40-50. I don't have any specific lots in mind, but there's usually plenty of them.
Tailgating: Indy is a great host city and the game will be played right in downtown. There will be a fan fest with concerts. (I think Sam Hunt is playing last I saw) Usually a couple of streets are shut down around the stadium and they set up food trucks and fan zones. As cold as it will be though, I'm assuming most folks will pregame around the bar scene around the stadium. Couple of notes below. If you're going that route, get to your preferred spot early or expect unreasonable wait times. This will 100% be the popular choice both for incoming travelers and locals.
Bars/Restaurants:
Walkable: Right next to the stadium is Tavern on South. It's a decent spot, and huge, right by a stadium gate. Road closures might make it difficult to get to, but it's your shortest walk. Slippery Noodle is kind of a ratchet dive bar, but it's also a close spot to grab pregame drinks. My personal go to spot is Elison Brewery, good beers, solid food, not far of a walk. A couple streets up into downtown you have Georgia St, which has a few restaurants. District Tap is great, there's also a Hooters, Punchbowl Social, and a couple other options. St Elmos, which is easily our most famous local restaurant is right up there as well. Another street up on Maryland St there's Yardhouse and a few other places. All of these are walkable to the stadium if you want to park around them.
Drivable: About a mile northeast is MassAve, which is a strip of bars and restaurants. The Eagle, Bakersfield, or St Joseph's Brewery are my go to options here. A mile east is Fountain Square, which is another district of bars/restaurants. Hotel Tango Distillery is pretty cool. These two aren't walkable, but may be slightly less crowded with better local food options before the game and should have decent temporary parking. 4 miles north is Broad Ripple, which is another cool spot of bars/restaurants. It's right by Butler University, so some local college flavor.
Transit: Don't expect much. We have a random bus system called the Red Line. Runs North/South into downtown. It's worthless and basically just takes up road space. But if your hotel is close by a station and you don't want to drive or Uber, that's about your only option. We do have an easy network of Uber/Lyft options, so that's your best bet.
Other Activities: There's a few other museums in the canal area about a mile from the stadium Eiteljorg is cool, also the NCAA headquarter and museum is right there. For families, our Children's Museum is world class. Easily one of the coolest spots in Indy. It's about 3 miles north of downtown. The Pacers (Our NBA team) are home Saturday. We suck, so tickets are cheap these days, but that's right in downtown as well. IU has a home game on Sunday, and a game at Assembly Hall is bucketlist for a lot of basketball fans. That's about 90 minutes south, so I might recommend that if you plan on driving up Saturday and want a cheap stopover point for that night. Butler University also has a home game Friday night. A game at Hinkle is awesome, like stepping back to a more raucous version of the 1950's.
(Edit: I’m sure the mods would prefer I add the disclosure that it’s neither supported or condoned by TF, but worth noting sports betting is also legal in Indy. If that’s your thing, We have a sportsbook downtown over by the Pacers stadium called Winners Circle. They have food/drinks and tons of TVs. I’m betting that will be a popular spot between the championship game and NFL games on Sunday)
Hopefully these suggestions help. Please feel free to DM me if you have area specific questions by your hotels. I can't wait to have us play in my backyard for the first time and look forward to seeing you all there!
