I am looking for a place not too far from Sioux Falls (2-3 hour radius) to which I can send my parents for their 65th anniversary. Looked at Lake Okoboji but the prices of hotels are $170 or more. I might be able to do a night for them but not sure if I have other options. Am thinking Lake Okoboji, dinner at Minerva's and back after a night at this point but it does get kind of pricey. Minnesota??? They have done Cedar Shore in Chamberlain before so I need another idea.
