Scenic Diamond

In-Depth Excursions: The guides — all local — know how to cover more than the basics when it comes to a destination, taking tours off the beaten path to show a different side of the city than what's in the guidebooks.

Scenic Sundowners: One of the new experiences on board: the British tradition of toasting to the sunset with drinks served somewhere fabulous overlooking the river, like a castle with sweeping views over the Wachau Valley in Austria.

Laid-Back Decor: You won’t walk into gilded rooms with chandeliers. Instead, you'll find sleek, modern designs — including marble-lined lounges — that focus on bringing the outside scenery in, since that’s really the highlight of these cruises.

Multiple Dining Venues: Scenic Diamond has six dining options, and all are top-notch — that goes for room service, too. Those staying up on the Diamond Deck are also invited to the exclusive chef’s Table La Rive for a gourmet six-course dégustation menu paired with sommelier-selected wines.

Groups: For people who travel together, these cruises are a dream everyone can go at their own pace (the ship has several tour options in each port) and regroup on board over complimentary pre-dinner cocktails up on the Sun Deck.

You May Be the Only American: The 30-year-old Australian company has gained a loyal following in Oz and is only slowly starting to make a name for itself in the States; it's a great group though, and you'll be surrounded by Aussies who know how to have a good time.
