I'm sorry to hear about the inconvenience you faced during your Cancun excursion due to the unexpected rain. It's true that cancellation policies can vary between providers, sometimes differing from Viator's policies. While our initial recommendation was to reschedule the activity for another day, I understand your concerns, especially when safety is a priority, especially for your grandmother and mother. In this escenario, the provider advises us the tour will be carried on a normal basis, if you decided to cancel, you will have to aqcquire the tour once again.
We appreciate your understanding, and if you decide to explore other ways to book excursions, we're here to assist if you have any questions or need recommendations.
Best regards
