They did not eliminate pre-10. What they have done is, apparently effective today because the updated members' benefits manual is dated today, switch from going to a specific dollar discounted rated to a percentage discount, 40% off regular rate after ten and 25% before 10. I believe that is worse than what they previously had but not all the time. And you still need the $50 annual card.
Note if you have an annual pass you can get a 30% discount any time of day. The new 25%
DVC discount for pre-ten times is worse than what we had before because what we had before was better than the AP discount for pre-ten times.
