We were also on the same cruise, and were pleasantly surprised that given it's size we liked Ovation so much. The decor felt light and airy, and we loved the couch in our balcony cabin.
After avoiding crowded lifts on the ship we were a bit shocked in the terminal to find the escalators out of order, resulting in everyone being crammed tight into the elevators. We never thought to ask if there were stairs we could use.
