If you are interested in comments about MSC cruises, I would suggest that your best bet is to go to Cruise REVIEWS, the big Orange button at the top of the page, then select MSC from the cruise line drop down menu.
Always do research on any cruise line, shore excursions etc before you book. Use this site or tripadvisor. check always to see if your question has already been answered.
