My husband and I from GA will be meeting our 26 yr. old son in SD in late Sept. for 5 nights. We will have one night alone, 2 nights with the son, and then 2 nights alone. I'd like for us to see SD and other towns around the area. We will have a car, and our budget is $200/night for hotels. It's our first visit, so I'd like to see and do as much as possible. It's my son's birthday weekend, so I'd like something special to do one day, either in SD or elsewhere. I've read the posts of sites to see and do in SD, but am looking for other options outside the city also. I have no problem with spending the night in other towns other than SD. We like a little touring and history, but also other fun things also. To stay some of the time on the water would be nice as your coastline is much different than our's. Thanks for your help and expertise!!!
