Review of MS Vivienne deck 4 (Sun)
On Sun Deck are located the Wheelhouse (Navigation Bridge), Sundeck Lounge (roof-covered and glass-walled), sunbathing area (spa pool, sun loungers), Observation Deck (with 4-seat tables), shaded seating area (with deckchairs, covered by awnings), deck games area (with Giant Chess Set).
All structures on Sun Deck (Wheelhouse, Lounge, awnings, railings) are collapsible and lowered when the boat passes under low bridges.
All decks are interconnected via stairs. One Lift (midship passenger elevator) connects decks 2 and 3 only. Outside staircases and a stairlift connect decks 3 and 4.
