TUI Cruises, the Hamburg based premium market cruise shipping company, says it will introduce 24 hour room service on board its two latest vessels, the Mein Schiff 3 and Mein Schiff 4.

The Diamond service will enable passengers to order drinks and light snacks to their cabins around the clock, such as tapas and wine. A charge will apply for the service, the company said in a statement.

The company has a total of four ships in service and it has fitted Nespresso coffee machines in all cabins to allow passengers to have coffee or tea without leaving their accommodation.
