"Operating out of Cambridge, Massachusetts, this company runs small-group tours for 10 to 22 guests with a senior-friendly focus on city experiences, national parks, history, and seasonal events like tulip season or New Year's Eve in major capitals. Solo tours provide private rooms, social events, and optional classes such as yoga and cooking, and clients can also form private groups and use the company's coordinators to plan custom departures." - Patricia Doherty Patricia Doherty Patricia Doherty is a writer who specializes in covering destinations, resorts, and cruises for Travel + Leisure and other publications.
