We will be stayijng at Treasure Island on 7-mile beach in February and were planning on renting a car the last 3 days of the trip (staying 7 days). We thought the 1st few days we would just hang out in the 7-mile beach area, take a tour to Stingray City and then on Wednesday rent a car for the last 3 days. There will be 4 of us (all adults) and we love to walk. Will we be able to walk to good restaurants or is this not really possible? Also, can we get to Georgetown either by walking or bus? Just want to make sure we aren't making a mistake by not renting the entire time. Thanks for all of your input!
