Wrong cruise line. You have been dreaming about 'Princess Cruises'.
............ or p&o Azura.
I have sailed on the Constellation on quite a few occasions along with her sister ships the Millennium, the Infinity and the Summit and none of them had an outdoor cinema.
Its an inside cinema thats used for some talks as well as films.
I have,on quite a few occasions watched movies in outside venues.Theres nothing special about it.
No outside film shows on 'Constellation'.
On 'Solstice' they set up an inflatable screen and showed a film in March on the pool deck but the ship was overcrowded with children and it was for their benefit.
