We are sailing on the Magic in July and we are interested in doing the trip to the Vatican museum, Sistine Chapel and St. Peters Basilica by private train. Has anyone done this trip, was it worth the extortionate cost? The main reason I want to do it is because it is the only trip to the Sistine Chapel. We will be travelling with a 13.11 and 8 year old. I would really appreciate some advice, I plan to do a lot of trips on our own but this one just seems to enormous to organise on my own!
