Mount Pilatus Summer Day Trip???

Hi All!

Has anyone gone on the Mount Pilatus Summer Day Trip from Zurich? I am planning to book my parents on this tour. They both are 60+ and would prefer not to walk up and down slopes during their trip. Can anyone tell me how much one has to walk on this tour? And that whether there is any walking to be done from the aerial cable car which takes one to the top of the Mount Pilatus.

Also the tour includes site seeing in Lucerne like the Lion Monument, Chapel Bridge and Jesuit Church. So again the same question - how much does one has to walk up and down slopes for these sites.

My parents dont have much problem in walking but they may get tired pretty easily if it has to be done on slopes as that is more tiring. Hence these points are pretty important for me to select a tour for them.

Thank you all once again!

PS: My father has had an angioplasty done in October 2008 but has since recovered very well....but still I want him to avoif thin airs....so can anyone tell if the cable car to the top of Mount Pilatus is closed and has heating and compressed air or does it have open windows???

Thanks again!
