We drove from Bar Harbor Maine to PEI
a few years ago which was about 400 miles with fuel and a lunch breaks, along with some secondary road construction, it was a the max for this guy. Traveling through New Brunswick has some steep hills and tow vehicle at the time was slow pulling up. You'll also have a 1 hour eastern Atlantic time change when crossing into Canada, which is more into the evening setup time on arrival. Its a beautiful place to visit, and with the value of the $USA
, its a great choice, but don't kill yourself getting there. If you take the wrong turn on the island, it adds some time...
