I am looking for a reliable travel agency that specializes in European tours. My group consists of 10 adults, and we are planning a 2-week trip during the summer. We want to visit major cities including Paris, Rome, and Barcelona. It is important that the agency provides a complete package including flights, accommodations, and guided tours. We prefer well-reviewed services and would appreciate suggestions for unique local experiences as well. The budget is around $5,000 per person.
