The glass lift on the outside is all glass including the doors, it only goes down so far I think to deck 8. they also have a glass lift in the middle of the ship which is all glass. Hope this helps.
The glass elevators are external so you get a view as you travel up and down all 10 decks but they have glass doors as well.
They have 4 lifts on the outside (2 on each side of the ship) with glass doors situated midships. The others are inside.
There are 4 `outside' lifts midship (2 each side) with glass backs overlooking the sea and glass doors and go from F deck up to the Sun deck. There are also 4 normal lifts (all enclosed) at either end of the ship and 2 lifts midship adjacent to the `glass lifts'. There is no glass lift in the middle of the ship as there is not an atrium like there is on Oceana.
