We booked this tour a month in advance. Sure glad we did! Peter even picked us up at our hotel, found the other two people and we were off for a FANTASTIC tour! He is so warm, very informative about the city, and the places he took us was by far more than we expected. DON'T take any trolley, only book with Peter!! When we return he will be the first one we call! His knowledege is second to none. Just look how bored the trolledy passengers look when they whiz buy, while we are stopping, taking pictures and listening too him. Small cozy tour cart, but very large in value. Thanks Peter for a fantastic day!!! You are the best!!
