We did it in Rome. A woman from NC studied history and art history there. Ended up marrying an Italian. Fwd 15 years and she was doing private tours. The experience touring St Peters, the Sistine Chapel, the Forum and the Colosseum was incredible. She had so much superior knowledge to anything else we could have done. I remember it so well 10 years later. Since then, we've done similar things in Thailand and Tokyo. Never been sorry.
