Promenade Park is Downtown Fort Wayne at the intersection of Harrison and Superior Streets. It is about a 5-10 minute walk from all three downtown hotels.
The pavilion and Promenade Park is on the northwest side of the park right by the Wells Street bridge. It should be fairly obvious once you arrive at the park. A map of the park can be found here: http://riverfrontfw.org/wp-content/uploads/2019/07/Promenade-Park-Map-Letter-Size-1.3.pdf
There is both street parking and garage parking close to the park. City lots 8 and 15 are probably your best bet, but there is plenty of other parking. For more information on parking, including a map, see: https://downtownfortwayne.com/parking/
What's a wedding without some liquid festivities? Yes, there will be a full cash bar at the venue serving Trubble Brewing beers as well as wine and alcohol.
Rachel will be in a pretty stunning dress. Andrew is going to be rocking a bow tie. That being said, you should feel free to come in smart casual dress. If you're unsure of what that means, ask yourself, "Would I go to a really cool person's bar mitzvah in this?" No shorts, jeans, t-shirts, tank tops, flip-flops, etc. You're all adults, you know what this means. Ties not required.
