It's been over 10 years since our first and only cruise. We're looking at a Carnival cruise in July. We are going to be moving about 38 days prior to our cruise, but don't yet know where our new address will be. Do they mail any documents I will need for the cruise one month or shorter ahead of time? We don't have our new address yet and based on a prior move, I don't have a lot of faith in our mail accurately getting forwarded to our new location. Do you think it would be better to use our in-laws address in order to receive any important documents we'll need from Carnival prior to our cruise? Or, is that not necessary as nothing really is mailed to cruise goers now? Thanks for your help!
