ABD is awesome ... but our first experience with pre/post packages was less than magical. We are frequent ABD/APs guests and have always felt we have been fairly treated by Disney until now. We added an additional person to an existing pre one night package and were charged $1K (no additional room or explanation as to why). Talked to the supervisor who could not explain the extra added cost..other than he said that is how the industry works? Excited about the trip, but this a definite downer - less about the money and more about the way we were treated. Lesson learned - think twice before you add a pre or post trip.
