Bob......Never been to Brackley beach, but I would consider setting up in three parks to tour from. The Island is some 175 miles long and your day trips may be spent mostly traveling. Souris(east end of Isl) has a PP with full hookups. Private parks near Charlottetown(central region) and many parks in the western region. The play..Anne of Green Gables is a very popular attraction.
