Deck 12 - Sanctuary pool, outdoor pool, Sanctuary guests only.
Deck 14 - Lotus pool, Adults only, indoor pool with retractable roof.
Lido pool outdoor pool, all ages.
I think the Sanctuary pool is being confused with the Lotus pool.
The lotus pool is indoors although the roof can open. It has two hot tubs as well. I used the pool and the hot tub a lot
