Let me start by saying that the actual ship is very nice and we had a nice trip.
PROS: The cruise directors, Andrew & Andy, were really fun. The entertainment was very good. We enjoyed the various trivia games, there was a great magician, awesome juggler, and very interesting high-tech lights\video\music act. The food was great in both formal dining room and buffet. They have great video screen at the pool that plays recent movies (that you can also view later in your cabin). There are fun "touch screens" on every floor where you can locate the people you are travelling with, see deck plans, the entertainment schedule, AND there is fun "explorer puzzle game" for the kids to play. There are 3 regular sized pools (one is private one for adults only near the spa), and one very small "kid's area pool", so there are different options. I think they make good use of the space and boat doesn't feel too large (or too small). Also, very "non pressure" from the staff. I've been on some cruises where they are always trying to sell you things, but this ship wasn't like that.
Stops on our cruise were awesome. In particular I loved Quebec City, & Prince Edward Island. Halifax is nice, but a bit more of a bustling city. Sidney Nova Scotia is cute town but a "young port" so tour options (e.g. if want to go to the Alexander Graham Bell museum) are limited if you don't book ahead. You can't even really even find a taxi.
E514 (Deck 8) is typical cruise room in size. We had two twins on ground, and two pull out "bunk beds". Small but manageable for 2 adults\2 kids. It is one of the better "obstructed view" cabins, because is located between the gap of two tender boats outside so you do have an okay view. It is mid-ship so very convenient to go to center "piazza" or walk to back of the boat, then up to the buffet on deck 15.
Biggest downside of this cabin is that is is DIRECTLY ABOVE the stage of the Explorers Lounge on deck 7. That is lounge where rock, R&B, and big band music is played by a live band. That means you will be subjected to extremely loud music on most nights between 9PM to 11PM. I'm not exaggerating when I say that you can feel vibrations of the band. Will effect you if want to go to sleep early or when watching TV at night.
All tours were sold out so we just walked around the town. Stumbled across some fun things (like Screaming Eagles Hockey Stadium near the casino), but this is small, young port with not as many shops or things to see as some other towns.
