If your cruise is a no-fly cruise, most cruise lines will allow you to take a good amount of luggage aboard provided it fits in your cabin and does not pose a safety risk. Please note that if on a fly cruise or using a transfer coach or train, you are subject to the baggage size, number and weight restrictions of the airline or transport company so please check this beforehand.
Azamara: maximum baggage weight is 90kgs
Carnival: 1 bag per person for cruises less than 5 days. 2 bags if the cruise is more than 6. Each bag must be no more than 50lbs and 40x60cm wide but no limit on height.
Celebrity: 90kg per cruiser (Galapagos ships are an exception)
Voyages of Discovery: 20kg per person
