We chose the MSC Seaside because it was brand new, and we had cruised on the MSC Divina 3 times and loved it.
We were in the Yacht Club which is the best experience you can have. You are whisked on the ship, have a beautiful suite, butler service, concierge service, your own dining room for breakfast, lunch, and dinner, Topsail Lounge for your exclusive use, unlimited drinks, your own pool area, with hot tubs and buffet, and "magic band" that brings the elevator to you, and does every thing you need on the ship. The only time you need your cruise card is to get on and off the ship. And speaking of getting off, you have a butler who takes you off the ship, so no waiting.
The ship is absolutely gorgeous! The theater is small, but we never had a problem getting a seat. The addition of water activities for the kids, and the slides is great. The zip line is long and fun (there is a weekly charge for it). There are numerous venues for music and activities. Our friends attended Trivia every day and said it was so much fun.
Absolutely stunning! The bathroom is extra large and gorgeous with rain shower! Fresh fruit in the cabin, mini-bar restocked daily, extra large balcony.
