We visited PEI with our children. I don't remember a lot of the places we visited and I guess it would depend on your likes/dislikes. I loved Anne of Green Gables site and the lobster meal we had one evening at a large hall was superb....expensive but worth it, as you could have seconds/thirds of all the homemade salads, preserves and desserts. We stayed near Cavendish Beach and just being near the beach was a big plus for us. We had an efficiency unit and cooked our big breakfast every morning and made sandwiches to take during the day if we went sightseeing. The beach area near the hotel had bbq pits so we often had bbq in evenings or a beach fire at night to roast wieners etc. I don't know if they allow beach fires now. Other visitors joined together for singalongs and other beach activities...very informal. We rented a car so we could visit but some areas are long walk-arounds...usually the park areas which were geared to the children. There are a lot of touristy things and plenty of small restaurants along the highway. Lots of this may have changed now as this was many, many years ago and was more a trip for the kids than adults. I would recommend booking early, as the whole island is a tourist place in the summer.
