Flight
Milwaukee airport is small, easy, close, and our favorite airport we've ever been to. However it can have more limited, pricier and longer flights than Chicago O'Hare Airport. We would definitely check both and try for MKE but do absolutely whatever is best for you. We are just happy you're coming and we'll figure out the rest no biggie.
Flight
We highly recommend that if you fly into Chicago, fly into O'Hare. Try not to fly into Midway. It's just not the best. But again, do whatever is best for you and we will figure it out.
Hotel
This is the hotel closest to the venue (it is very very close). If you are wanting to be close to the wedding and out in more rural Wisconsin, this is great. It is also super close to Lake Geneva which is an adorable little town on a beautiful lake. But if you are wanting to explore Milwaukee during the weekend, maybe not the best spot for that since you will be 45 minutes outside the city.
Hotel
This is a gorgeous old home that is 6 minutes away from Camp Wandawega. It has multiple rooms that can each be booked individually on their website.
