Review of MS Viola deck 4 (Sun)
Navigation Bridge (called Wheelhouse on riverboats) can be lowered when the ship passes under low bridges.
Adjacent to the Wheelhouse is the Sonnendeck Lounge - retractable (roof-covered) structure with Lift-Staircase access, indoor table seating, and bar service.
The spacious Sun Deck is furnished with plenty of sun loungers and deckchairs. Sun Deck also provides passengers with the opportunity to enjoy outdoor fun activities - playing cards and popular board games, as well as dancing with live music performances (in the evenings).
Ship's top-deck area is fitted with two collapsible structures - the Wheelhouse and the glass-walled, roof-covered bar lounge. They are retracted/lowered and off-limits (not accessible to passengers) when the riverboat passes under low bridges.
One lift (wheelchair accessible passenger elevator) connects all decks.
