It was our second cruise on the Oasis, and it was once again fabulous.
We were 6 adults, 3 rooms. We booked two inside promenade view staterooms, deck 7, not as good as I was hoping for - some of the views were obstructed, some extra noise and light into the room. Still they made for a good choice. Also booked one of the balconies overlooking the rear aqua-show pool, deck 8. That was a good choice, but once you do it once, there are other choices for next time. The rooms are smallish.
Activities were superb. Shows and entertainment were good.
