We are working a college visit to USC in Columbia into a Spring Break trip in March. It will be myself, my mom and my 17 year old daughter. We will fly into Charleston and rent a car. Currently planning to stay 4-5 nights between the two places. Any suggestions for B&B's to try that can accommodate 3 in one room? Thinking $225/night is the budget. How many nights in Columbia and how many in Charleston? One whole day will be college tour but we can cram that into a day trip if not much to see/do in Columbia. Thanks for the help!
