The day continued with lunch, a cruise around Sydney Harbor, and a guided tour of the Sydney Opera House. Our pedometers were melting down by that point! Fortunately we had the evening free. Most of us just had a light dinner and glass of wine at the hotel - too tired to explore the nearby eateries.
Several of us have had bad colds and one fell on the stairs, so we've had significant first-hand experience with the Australian medical system. Fortunately the medical care is readily available, top quality and very inexpensive. We're on the mend!
