We have booked a block of rooms at the Sheraton Duluth Hotel for June 24th and June 25th. The cut off date for reserving rooms in the block is one month prior to the day of arrival. Mention the Puhl/LeBlanc wedding when booking. This hotel is connected to Greysolon Ballroom by skywalk.
There is not a block of rooms at Fitger's, but it is a beautiful option located just down the street from the reception.
