The Field of Dreams has roughly 100,000 visitors per year. They guesstimate 2,000 people tour the home each year as they do not track the visitors.
It just opened this year, its tough to give an exact number. Its probably not extremely high.
Not sure of the number, but I believe you have to book that in advance.
There is no way to track the amount of visitors. There are more that attend the games and the events. People come all months to tour field and house so it's hard to know for aure
