MS Geoffrey Chaucer deck 3 plan (Upper-Diamond-Lobby-Lounge)

Diamond (Upper) Deck is the riverboat's Lobby (Foyer/entrance hall) with a Reception Desk (24-hour assistance, information, purser services), Travel Desk (tours and excursions information, onboard cruise booking), and Boutique Shop.

From the entrance hall is the access to the fore-located Bar Lounge (Panorama Lounge) with floor-ceiling windows, comfortable seating, a full-service Bar, and Lido Terrace (bow-located, with small outdoor seating). Panorama Lounge also serves the cruise company's enrichment program with cruise tour itinerary (ports and excursions) related daily lectures and media presentations, as well as nightly entertainment program with live music performances and dance parties.

Aft is located the Bistro - Lido Restaurant, an alternative to the Dining Room Restaurant. The Bistro is served by its own Bar and also doubles as Library. It has an outdoor terrace and an open kitchen. Here are served early Breakfast, light Lunch, and Dinner. In good weather, the floor-ceiling window doors are fully opened onto the terrace for al fresco dining. Bistro's dining is complimentary, but dinners require reservations due to the restaurant's small capacity  (10 tables with 2 or 4 seats).

All cabin decks are fully air-conditioned and accessed via lift (passenger elevator) and wrought-iron staircase.
