The easiest airport to fly into is Milwaukee Mitchell International Airport. You will find the most flights going in and out of this airport, and Kohler is about an hour drive north of Milwaukee. An alternative option would be Dane County Regional Airport in Madison. This is a smaller airport and you will likely need to make a connecting flight to reach it. Kohler would be about a two hour drive northeast of Madison.
Wisconsin weather at the end of June is typically warm during the day, but it will likely cool off at night. Make sure to bring layers to keep warm after the sun goes down!
The "dress code" for the wedding is semi-formal/cocktail attire.
Yes! They are all of ten steps away from each other. Unless you take small steps, then maybe it's closer to fifteen.
Unfortunately, we have decided that the wedding will be adults only.
