Choose the Sky as we wanted to go back to Atlantis and to Key West for the first time.
The Sky is an older ship but was in decent shape. We're told it was going for a dry dock right after our cruise and thankfully we saw no pre work being done.
The entertainment was Decent and the food was average. We found the Dinning room sub par compared to other Norwegian ships. The specialty restaurants were good. We went to the steak house and the Italian restaurants.
Cabin was in decent shape. We found 3 fit perfectly.
The balcony is huge but being at the front you get the wind directly so not great when at sea. We had a rough ride on the final night I think being at the front made it worse.
Location is quiet, there is a door to the adjoining room but we never heard anything from the other cabin.
