Hello! My daughter is studying abroad in Nantes, France. She and fellow students have a holiday coming up and she will have the possible opportunity to travel for 4 days or so. She is on a limited, frugal, frugal budget, but wants to see Europe while she is abroad. Where should she go for 4 days? They have considered Rome, but that is getting expensive for flights at this late date. Any ideas out there?? She loves history and culture stuff!
