Thanks so much to everyone who has already sailed for posting about your experiences! Can anyone speak to what younger children have enjoyed or might enjoy? Mine will be 6 and almost 2 - I don't see them spending a couple of hours appreciating the Citadel or any sort of shopping! We sail on August 5th - this is our first cruise ever and I've done no research or planning yet . . . the panic is starting to set in!
Once we left the ship to explore the ports, our kids (6 and 5) wanted to go back to the ship to Oceaneers Club or Lab or the pool! Good thing we did not book any excursions! We just walked around the pier and boardwalk in Halifax and walked to the main streets of St John both an hour each and then went back. You may want to look into the Theodore Too tour in Halifax or the Museum tour with the knot lessons for kids also in Halifax.
Our table mates at dinner (a family of 4 with a 6 yr old and a 4 yr old) did book excursions in both ports. In Halifax they did the Hop On Hop Off and they said they enjoyed that. In St John they did a Bay of Fundy Tour with lunch and the father said it was not worth it. He said they spent more time traveling on the bus than actually at Bay of Fundy.
Hope you enjoy your first cruise! This was our first DCL cruise (we've been on other cruise lines) and we were very impressed with the service and the quality and quantity of the entertainment.
