Anyone Biked on P.E.I. or the Iles de la Madeleine?

We're planning a cycling trip (a combination of trailer camping and B&B stays) on Prince Edward Island and the Iles de la Madeleine (which you get to by taking a 5-hour ferry ride out into the Gulf of St. Lawrence from a port in P.E.I). We've been to P.E.I (by car) but never the islands, so there's a certain amount of "chicken trip" going on. Our plan is to leave our van at the ferry dock when we arrive and do the rest of the tour with minimal packs (with nice meals and soft beds awaiting us at a variety of inns and B&Bs, eh hem). Not exactly roughing it, but without the security of a warm car if it rains between stops.

Both have reputations as great touring destination for bikers. If you have any stories to tell, accommodations to recommend, or must-see-sights for our trip, we'd love to hear 'em.

Note: That's not my family there, but that's a genuine photo of biking on the Iles de la Madeleine. Thanks to the Tourism Bureau of Iles de la Madeleine for the photo.
