Crowd InformationHolidays and major events can attract large crowds to Wisconsin. For example, accommodations in small towns like Hayward and Cable sell out during large events such as the American Birkebeiner. Christmas and other holidays are also a very busy time at family-oriented places. Fall and spring have the fewest crowds because kids are in school. Throughout the year, there are fewer crowds midweek than over weekends.
Closure InformationSome shops in northern resort towns close for the winter, but most remain open and reduce store hours instead.
When to SaveIn general, summer tends to be the most expensive time to visit, especially on weekends. The rest of the year is cheaper, particularly in spring when good deals are usually offered. No matter what season, the best deals are always for midweek travel. Northern Wisconsin and popular tourist areas such as Dells, Door County, Bayfield, and Northwoods will be pricier and booked solid during August. Major cities such as Milwaukee and Madison tend to be busier when business conventions are in town.
When to BookIn general, book one to three months out to ensure the best choice of accommodations. However, last-minute types who don't mind risking the chance of availability may be able to find deeper discounts on air and hotel by waiting until less than a month in advance to book.
