We have never purchased APs before but have been going to Disney twice a year. This year we are thinking about taking a third trip, so APs will definitely save us money. However, I'm wondering if there is any drawback to AP, which may be preclude us from package deals. For example, we are booked in a package over Labor Day that is basically a room discount but requires a minimum ticket purchase. Also we often travel with my parents who do not have APs. In the past, we have done villas with them. Will this be a problem if we have APs and they have to buy tickets?
