I booked 6 tours in Costa Rica through Viator. Five of them were good, two of them were particularly outstanding. However, one of them didn't provide everything listed - it was a horseback riding tour that also indicated a stop at a Rancho where tortillas and fresh cheese would be provided. Alas, we only got horseback riding. The tour was great apart from the unmet expectations. Viator's excuse was that it didn't indicate which tour provided the food - well, yes, the tour I selected and paid for! - and declined the partial refund I requested. Invalid reasons and disappointing.
