Review of MS VistaExplorer deck 4 (Sun)
The fore-located Navigation Bridge (called "Wheelhouse" on riverboats) is passenger-accessible.
On Sun Deck are available shaded seating area (retractable awnings, 4-seat tables) and sunbathing area (deckchairs and sun loungers). Sundeck's fore-located Sky Lounge is roof-covered and glass-walled.
All structures on Sun Deck (Wheelhouse, Lounge, awnings, windscreens, railings) are collapsible and lowered when the ship passes under low bridges.
One Lift (midship-portside elevator) connects all cabin decks. All decks are interconnected via stairs (forward, midship and aft).
