Quick answer: If the operator cancels, you are entitled to a full refund or an alternative date — on every major platform, regardless of the product’s cancellation policy, including non-refundable tickets. Accept the alternative if it works; otherwise ask for the refund in writing through the platform. Then use the platform’s support to rebook something similar the same day — Viator’s 24/7 team can usually find a comparable tour with availability. What you generally cannot claim is consequential costs (a taxi to the pier, a hotel night), which is a travel-insurance matter.

Top-Rated Santorini Tours & Experiences on Viator
Step 1: Confirm It Is Actually Cancelled
Cancellations come by email, text, app notification or a call from the operator, sometimes the morning of the tour. Screenshot the message. If you only suspect a cancellation (nobody at the meeting point), call the operator using the number on your voucher; a no-show is handled the same way as a cancellation but needs evidence — note the time and photograph the meeting point.
Step 2: Alternative Date or Refund?
Operators usually offer another date first. If it fits, take it — you keep your booking and the price. If not, reply in writing (through the platform’s messaging or support chat) that you want a full refund. You do not need to accept a voucher or credit; a refund to your original payment method is your entitlement when the operator cancels.
Step 3: Get Rebooked the Same Day
This is where the platform earns its commission. Contact Viator support (or the equivalent) and ask for alternatives: another operator running the same route today, a different departure time, or a comparable experience. On popular routes — Santorini catamaran cruises, Mykonos day trips (see the tours above) — there is often availability, and support can see it faster than you can.
Weather and Minimum Numbers
Boats, flights, balloons and mountain activities cancel for safety; small operators cancel when a minimum group size is not reached. Both are legitimate and both trigger the refund-or-alternative rule. Booking early in your trip gives you room to rebook weather-cancelled activities later. Details in weather cancellations and no-shows.
Late Notice and Repeated Cancellations
Very late cancellations (after you have travelled to the meeting point) still only entitle you to the refund; consequential costs are for travel insurance (what insurance covers). If an operator cancels repeatedly or with obviously false reasons, report it through the platform — it affects the operator’s ranking — and leave an honest review once the case is closed.
If the Refund Doesn’t Arrive
Refunds typically appear within 3–10 business days. After ten, contact support with the cancellation message and ask for the refund transaction ID. If the platform refuses a refund for an operator cancellation — rare — a card chargeback for “service not provided” is appropriate; see refunds and chargebacks.
Reduce the Odds
Choose operators with hundreds of recent reviews and few cancellation complaints (search the reviews for “cancelled”). Prefer operators with multiple daily departures. Book weather-dependent activities early in the trip. Keep the operator’s number and reconfirm pickups the day before.
