Hop-on hop-off bus tours are great ways to explore cities especially when you have a large number of place to see in a short period. Visiting a city for the first can be quite intimidating and it is not difficult to get disoriented. Moving from one attraction to others can be difficult. the last thing you want is wasting your precious time in the middle of the road without enjoying your tour. Site seeing bus tours are smart ways to overcome this.
Once you purchase a hop-on hop-off bus tour it is valid for 24/48 /72hours. You can get on from one attraction and get off from another attraction. There is a continuous flow of busses so minimal waiting time. If you prefer distant viewing you can continue the bus tour without getting down.
Paid attraction ticket prices are not included in bus tours but you can buy them for a discounted price if you combine a few of them.
