My husband and I are on a budget friendly vacation to SD in late Aug. probably 20-25th. We would like to see the sites most tourist want to see, Rushmore, Caves, historical sites and decided Custer was a central location. I would like to reserve a cabin in the state park, but was unable to locate any that had bathrooms inside the cabin. Since I will be six months pregnant I didn't think I would need to travel far in the middle of the night to the facilities.Do any of the cabins have bathrooms? I checked the website and didn't see any. Are there any inexpensive comprable cabins in the area? Does anyone have suggestions?
