We had the morning free so we went for a walk after breakfast. After walking about 5 miles (easily!) at the zoo , we were glad the world's largest square wasn't far from the HJ (Howard Johnson) Hotel. It is incredible. Surrounded on 3 sides by modern buildings and on the 4th by the Bay. Swimmers were out in force as were children playing. The entire square is surrounded by sculptures depicting the different Olympic events. It's part amusement park, part beach, part green space and all business!
All in all, it was a great holiday.
