The Disney Parks blog just released a fascinating video of the new Skyliner system:

Apparently each cabin will be able to hold 10 people, including wheelchairs. The upper windows of the cabin can open up for more airflow, and view is amazing – you can see all around and below the cabin! I hope this is open by the time Galaxy’s Edge opens!
