Non-expiring tickets. Non-hopping tickets. Every ticket used to include BOTH hopping and NEVER expired! It was actually something they touted in their ads! If you've only been going to WDW for ten years, then those pre-date your visits. MYW started in 2005. That said, four day hoppers in 2004 were $192-$202. In 2005, the new 4 day non-hoppers were $185.
It depends how far back you go in visits to WDW.
They've also added the no-show ADR fee. I've never been charged it, nor did we abuse the system before it was added, but for me, it does make me reluctant to book ADR's. Especially when WDW so very often seats us very late past our ADR time. Last trip, we made it on time, despite the monorail not working 100%, and waited over an hour past our ADR. WDW doesn't hold up their end, but they want to penalize me if I don't hold up my end?
WDW also used to offer a kind of after hours event in MK for a mere $10. Three hours in the park, minimal other guests- just $10! Few folks knew about it.
Ah, but there I go again posting some history.
And WDW perks that were semi-secret.
Honestly, just as nobody knew about the $10 nights, I think many guests won't even know about this program.
