I am in the process of planning a 3 day trip to Vienna for around 10-15 people. In addition to visiting a museum each day, we would like to do a walking and driving tour for each of the three days. I saw that you have 3, 5 and 7 hour tours. Is it possible to do the 3 hour driving tour one day and then a two hour walking tour the next with a drive to MELK Abbey another day? If you could also give me a total cost per person that would be very helpful.We are planning on visiting March 8-12.

Thank you!
