My wife and 15 month old son and I just returned from a week long cruise aboard the Celebrity Summit. Cruise departed from Cape Liberty, NJ and sailed to King's Wharf, Bermuda. The embarkation procedure was efficient and quick, this was my third cruise and my wife's 10th cruise.
Overall impressions: Child care: The Toddler Room in the Fun Factory was perfect for my 15 month old. The room was approx. 15 x 15 and had plenty of age appropriate toys to use while there. They also allow you to borrow a "treasure chest" of toys to keep in your cabin for the week - our son loved this! The only downside of the childcare program was that the only public bathroom on the ship with a changing table is located on deck 11 by the Fun Factory. Also the majority of the high chairs we used had broken safety straps. Also keep in mind that most cabins do not have a bathtub, we anticipated this and had brought a blow up tub to use which doubled as a little pool for him.
Food: Food was good, not great. We had sailed on the celebrity Galaxy 3 years ago and the food was much better then. The portions served for dinner courses were on the small side, but the waiters will bring you additional portions if requested.
Very small, although a lot of storage space.
