We are visiting Disneyland this summer in late July. Can any one give us some advice on the best place we can get tickets, and the best time to buy them. We are staying at the Best Western Mini Suites, and it will be myself, my wife, and our 4 boys, ages 10, 9, 7, and 5. We are planning 2 days with one at each park. Any suggestions as to if we should add a park hopper.
