We are a 50-something couple who has cruised with family before. This was our first cruise by ourselves. In general, we had a great time. We only did one "excursion" and that wasn't through the ship. But we did manage to see a lot!
Here's a summary of what we did each day:
Day on the water: Explored the ship, read a lot, sat in the Thallasotherapy pool, worked out at the gym.
Room 6021 is a decent one, with a Sweet Sixteen (larger) balcony. We did hear some bass notes from the theater below us, but it wasn't bothersome.
