We sailed the Mariner of the Seas on 10-10-10. I'd have to say our cruise was about as close to a perfect 10 as we could hope for with our family. Great fun, good weather, lots to do on and off the ship.
Embarking went fairly swiftly. We arrived about 1, found a porter, and checked in after waiting in a line for less than 10 minutes. After the obligatory SeaPass and boarding photos, they turned us loose on the ship. We explored our rooms and the upper decks with the sports and Adventure Ocean until dinnertime.
ROOMS: We had a D1 balcony on Deck 7 and our 4 kids (14, 11, 8, and 5) were across the hall in an inside cabin. We liked this arrangement and always felt safe with it. Four kids in an inside wasn't too crowded to sleep in but storage was an issue. We saw our steward frequently and while she wasn't gushing/friendly, she was efficient and kept them clean without disturbing us.
