CHASE stuff:
For the past 2 years, Chase Disney Visa cardholders have been given the opportunity to book the special events one day prior to the general public booking date. (I can't recall if it was just the Disney visa or any Chase card but I think it's just the Disney visa. Someone will remember it). However, there are only limited spaces to prebook available for each event, so if you don't get the event you want you have to call back the next day and take your chances with everybody else.
Other than that, the only real Chase perk is the Chase Lounge, and any Chase card will get you access to that.
