Are there any age restrictions? Children are welcome on the tour, but please bear in mind that some children have a limited attention span and therefore a 3 hour tour may not be appropriate for them. Parents know their children best and should assess the situation individually. Since there is a lot of standing and walking please consider this when deciding whether the tours are appropriate for your child. Also, the tours require a certain level of physical stamina. For our walking tours, we are on our feet for approximately 3 hours. How physically fit do I need to be to enjoy this tour? Tours walk at an easy pace and cover approximatley 1 mile of walking. Our tours are generally appropriate for all ages and fitness levels, but please use your best judgment. Is smoking allowed on the tour? The tours maintain a no-smoking policy. Does the tour guide accept gratuities? Gratuities are greatly appreciated, although not mandatory. Are cameras allowed on the tours? Yes! In fact, we strongly encourage participants to take photos during the tour. However, we do not allow video cameras or tape recorders.
