Depending upon how much data you expect to need or want, you might just be able work with what is on your current plan. Your hotel should have WiFi, and your US carrier probably has US WiFi calling available. MSC will have WiFi plans available aboard the ship, but you will be in port enough you'll probably want service before and after the cruise. I am familiar with T-Mobile roaming services and visit Europe once or twice a year just using my current plan. AT&T & Verizon have options also, but they do not seem to be as generous with their roaming services on most plans.

There are several forum regulars who are able to give solid advice once we hear what your goals and current options are, so consider sharing that information.
