Tour cancellations occur when planned trips or excursions are called off, often due to unforeseen circumstances. Common reasons include bad weather, safety concerns, or low participation numbers. When a tour is canceled, participants are usually informed in advance and may receive a full or partial refund, depending on the tour operator's policy. Travelers should be aware of cancellation policies before booking a tour. It's important to read the terms and conditions provided by the tour operator to understand the options available in case of a cancellation. This helps ensure a smoother experience and minimizes potential losses.
