In the event of a cancellation, the response will basically adhere to the terms of the contract (terms and conditions). Check to see if there is a policy in case of inclement weather. If there is no agreement for inclement weather, even if the weather forecast is for inclement weather, the cancellation may be for personal reasons, unless the business decides to cancel the tour. In these circumstances, if there is a provision in the terms and conditions regarding the cancellation fee for personal reasons, the cancellation fee will be charged accordingly. If you are charged a cancellation fee that is not stipulated in the terms and conditions, ask the business to explain the basis for the charge and discuss the cancellation fee.
