We really liked this trip - our guide, Roger, was excellent, very informative. We had a little over two hours at the monastery, which was enough for a guided tour, the cathedral and the art museum. We only saw the madonna from far away - didn't know you had to reserve tickets for that ahead of time and there was a long line. Took the cable car down to meet the bus and then went to lunch. The lunch was plentiful and tasty and we had a nice chat with our group over wine. The groups are small, we had maybe a dozen people. Would recommend this tour!
