Hello, my 2 sons and their 3 friends are traveling for 3 weeks in Europe. All five are attending Harvard University and/or Stanford University and hope to take advantage of their education from their Western Civilization classes. We live in San Francisco and I am a Managing Director at Barclays Bank. I will be handling all the financial arrangements as well. I look forward to hearing from you and could use your advice on obtaining advance tickets to the Vatican and the Galleria Borghese if possible.
