Can I change my plans if I’m unsure - even though official advice still allows travel to my destination? For example, if I have a pre-existing medical condition.

Unless official advice is against travel to your destination, the property’s normal cancellation policy would usually apply. Travel insurance policies would also normally only cover destinations where the government of your home country has put in place restrictions.

The property may agree to a later arrival date, or an exceptional refund - please discuss this with them directly using the contact details in your confirmation.
