I had the opportunity to sail on the Seaside on her crossing over, and by and large I was quite impressed. The balcony staterooms felt roomy, although storage was a bit of an issue. The shows on board were very good, and I really enjoyed the specialty dining on board. Loved that most of the restaurants were in one area of the ship with a shared bar, it felt very deluxe - although the bar service there needed some work. Service was very good in Butcher's Cut, and really enjoyed the Sushi menu in the Asian Market Kitchen. Loved the French bistro in the atrium as well. The cheese board was awesome, and served from the tray tableside which was a nice plus. Buffets and dining room were average, but passable for me. Downsides for me included the fact that there seemed to be a lot more extras this time around. The bar in the bistro didn't offer any drinks that matched with my beverage package, even though the prices did. Although I managed to take a tour of the spa, I thought dayspa pricing was a little high at $60 per person.
I enjoyed the gym, and took the yoga class which was good - although I would have preferred a more traditional yoga class. I've sailed the Divina before and this is a big leap forward, and I would definitely sail again, especially once the ship has had more runs in the caribbean and the crew gets its sea legs.
