In the room before Rey's transmission there are two doors, each leading to a transmission room that is a mirror of the other. This is similar to the two stretching rooms in the Haunted Mansion. Here they are both:
Another photo of the great hologram effect:
There are 2 large screens that show Poe Dameron and Lieutenant Bek:
After the hologram you are rushed outside, where you wait for the door to the transport ship to open. This is outside, but almost entirely covered by overhanging rocks, which you can see a little below. I have seen some people ask about what they'd do when it is raining, but I don't think that this is an issue at all.
This was last night and the view from the window behind Lieutenant Bek is dark. When we rode it in the morning it was light outside. Also there are panels in the ceiling that were bright in the morning (and became dark when you arrived in space), but they were already dark from the beginning in the evening.
I really like this whole pre-show of getting tractor-beamed into the Star Destroyer. It is very well done. The same door you entered from suddenly opens and a First Order officer comes inside.
Looking back at the transport vehicle in the Star Destroyer, now with closed door after everyone exited.
Suddenly being in the Star Destroyer hanger bay is a huge shock and a magnificent view.
