Hotel
Reserve your room through the link below for our wedding block discount and get your room for for $189 plus tax! This is a busy weekend for the city so there's only rooms with one king bed available for the discount. The hotel is in downtown St. Louis, about a 15 minute drive from the wedding venue, 0.5 miles from the Gateway Arch, and right next to Ballpark Village (restaurant/bar area).
Flight
St. Louis Lambert Airport is the most popular airport in the area. It's about a 30 minute drive from the wedding venue and about 20 minutes from the hotel.
Train
I've used this train station to travel from St. Louis to Chicago; it's a great, cheaper alternative to flying and is only a 15 minute drive from the wedding venue and 5 minute drive from the hotel.
Rental Car
The airport offers rental car services from Alamo, Avis, Budget, Dollar, Enterprise, National, Payless, and Thrifty. More details can be found through the link below.
