Aladdin’s Oasis is becoming a Tropical Hideaway. Walls are now up and demolition is underway. Here is the original DisneyParks Blog Announcement from February. For a more in depth look at the artwork be sure to visit our full picture set from Disneyland on 5/25. The Oasis entrance structure is now completely removed.
It appears the Cave of Wonders set is still there.
