I was a Disney Store part-time regular CM at our local mall location from Aug. of '09 to Oct. of '13. I was also a Lead Mgr. there for about a year, until I stepped down from management after my old architectural firm hired me back part-time under contract. I've now been back with my old firm full-time for 2+ years.
Anyway, I started out getting a 20% merch. discount, and 1 Comp Pass for myself and any dependents in my household (5 at the time) every 6 mos. My merch. discount went up to 35% after 3 years with TWDC.
Also, I got a 50% discount on the DDP (we have never gone during "free" dining), and a 60% discount on the resort.
Our ASM and SM automatically received Silver Passes. These came with a 35% merch. discount, etc., and they could also get themselves and 3 other guests/dependents into any Disney Park worldwide for free on any day, except where blackout dates might apply.
