We have an all included package that has wifi, gratuities, and classic drink package. Question is once on board can you upgrade to Premium for the price difference i.e. classic package cost is $89.00 and premium is $109 so can I just pay $20 to upgrade? Also most cruise lines allow you to bring a bottle or two of wine/champagne on board does Celebrity allow this? We usually cruise Azamara and they allow you to bring alcohol on board as it is included in your fare so they do not care if you bring your own apparently as it does not cost them any money.
