Just got back from sailing. The solarium wings are a nice out of the way place to go, but they are not open during sailing. Also, the 'hidden' balcony is in the back by the rock climbing wall on 6 and 7. There is even seating and it was completely empty. 🙂
As for ice skating, it did open, but in the evenings on weird days. It said it was going to be open on Costa Maya day, so we went, but it was CLOSED. Annoyed it was on the schedule but no one there.
We had a great vacation. She is a beautiful ship.
