Deal watch: Buy one cruise, get another free

MSC Cruises is out with an unusual offer that brings two cruises for the price of one.

The Europe-based line says customers who book an all-inclusive package for a Europe voyage on the 3,502-passenger MSC Divina by the end of October can take a second cruise on the ship while it's in the Caribbean for free.

MSC's all-inclusive packages for MSC Divina cruises in Europe start at $1,899 per person for 10 nights and include round-trip airfare to Rome or Barcelona, a seven-night cruise, a two-night post-cruise stay in a four-star hotel, and all transfers needed — including from the airport to the ship, from the ship to the hotel and from the hotel back to the airport.

The MSC Divina will be based in Europe from May 16 through Sept. 19, 2015. It's currently in the Caribbean.

The free Caribbean cruise must be taken by the end of this year, and is transferable (it can be given to friends or family as a gift). Customers must choose from one of four available departure dates for the Caribbean cruise, which will be a seven-night trip: Oct. 18, Nov.1, Nov. 22 or Nov. 29.

Customers on the Caribbean cruise must pay all incidentals outside of the base cruise fare, including government fees and taxes, and service charges.

The included airfare in the Europe package is from the gateway cities of Miami, New York and Chicago. The MSC Divina's Europe sailings depart from Civitavecchia, Italy (near Rome) and Barcelona.
