Home - The Holy Land Experience
About a year and a half ago, the park changed ownership from a local ministry to TBN. One could see the influence was going from a more traditional, even slightly reformed emphasis to charismatic/pentecostal marketing and promotion (e.g. the book store promotions, contemporary "worship", and all the nonsense that entails, etc.).
All-in-all, this is a great place to study, explore, and be entertained by Old and New Testament history. A large replica model of the Temple before 70A.D. is there with very informative presentations. The "Scriptorium" alone is worth the price of admission. There were several Christians with some Jewish ancestry working there who were particularly friendly, informative and personable. The employees of all kinds (actors, singers, tour leaders, speakers all seem to enjoy their jobs. Children, especially will enjoy getting photos with Bible characters. There are several kids activities, too.
Package deals usually offer the best value and since 3 consecutive days at Disney requires great stamina from everyone, you might get a 2 day Disney Park pass with 3 nights at the hotel and spend the third day at the Holy Land Experience.
Also, regarding the long waits in line at Disney. If you are can be organized together while there- a service calculates wait times in line and the most efficient times of day, and produces a schedule for you:

I found this well worth the price, and hardly stood in line at all, even on a busy day.
