Hoping to get some quick thoughts. Off on Sept 7th NY/Canada cruise with a almost 4yr old and almost 1yr old. I know we'll need some sort of stroller for the little guy, but wondering which stroller I should bring. We plan on doing the Hop on Hop off bus in Halifax and the Saint Johns Highlights tour. I'm wondering how much walking will be involved and if a double stroller is necessary? My 3yr old is good to walk for about 45 min (and obviously my baby not so much). We'll have a carrier for the baby too, so I'm thinking we could even bjorn him if my 3yr old needs the stroller? My oldest doesn't nap anymore so we wouldn't need the stroller for her for naps either.... What do you all think?
