Surely you think that if when you book your cruise it is canceled at the end, you have the right to a refund of the amount of what you have entered, and that if you have paid it in full, this refund is in full ... well, it is not always like that. What is clear is that before a cancellation you have the right to claim, as a consumer it is your main right, from there many details are in the small print.
I am going to tell you some of the rights that as a future cruise passenger you haveThese are detailed in the regulation on the rights of passengers traveling by sea and inland waterways.
As a rule It is considered that the cruises are contracted under the modality, of at least two of these requirements, transport, accommodation or tourist services. This detail is important, because it will affect compensation.
Your first right is to access information throughout the journey. In case of cancellation or delay, it must be reported at least 30 minutes before the scheduled departure time or as soon as the circumstance is known. If this delay is more than 90 minutes or cancellation, the company that charters the cruise has to provide basic care to the passengers, and this includes accommodation.
People with disabilities or reduced mobility have the right to be guaranteed non-discriminatory treatment and free specific help they need, both on board and in port.
But what I was telling you at the beginning, your main right is to complain, it is mandatory that cruise companies and operators have their own complaints handling system. So you have to complain to them and, if after a month you have not received a response, with a resolution of accepted, denied or under examination, you should know that they have one more month to definitively resolve the claim. If this answer is not given, then you would have to go directly for the Consumer Law.
