We all have our favorite lines.. we all tend to pay attention to one cruise line more than another...my question is
Would you consider yourself a very knowledgeable or expert when it comes to a specific cruise line? if so which one?
Larry they normally substitute another port of call for one they miss.... and if you read the fine print.. in the cruising contract they retain that right...
I don't think anything "formal " was set up....it may be prudent to research all the islands that holds an interest to /for you then compare notes when our "expert" gives the report!!
