The itinerary was fabulous, but of course that is a reflection of the geography and not the ship: Barcelona, Marseille, Genoa, Naples, Tunisia, Mallorca, and return to Barcelona.
All staff members were pleasant, but none really went out of their way to be helpful unless specifically asked for service.
Unlike other lines I have been on (Royal Caribbean, Princess, Celebrity), the MSC Orchestra does not offer any food service (other than paid room service) beyond the set dining times. And as unbelievable as it sounds, there is NO COFFEE OR TEA available other than at breakfast -- the machines are shut off promptly at 10:00 AM. No coffee after an evening meal. No afternoon tea by the pool. Ridiculous! Espresso is available for purchase at cost of about one Euro; that's it. All other lines I've sailed have 24-hour beverage-and-snack bar service, and I sorely missed it.
