Here is a another fine venue to host a wedding in year round! If you're a member you get 10% off as well!
The MN Landscape Arboretum has Five gardens that will host 75 - 200 people and an indoor space for your reception. There is usually an artistic display going on in the gardens that heightens the experience even more. It is also close to the twin cities.
