We decided to take the larger group tour as opposed to the small group tour strictly due to the pricing of the excursion. It was fine being in the larger group. The only thing negative about this day was our tour guide was not easily understood. Since this is such a historical city it would have been nice to really understand all she was saying. The Vatican Museum was nice, but I could have skipped that and spent more time in the Sistine Chapel. St. Peter's Basillica is amazing. This tour was fast paced, but well worth seeing. Here's hoping you get a clearer English speaking guide!
