I was actually thinking about my future with tickets. Right now I have an AP and I'm going to have one next year. After that, maybe some trips where I decide to do a minimal amount of days for the actual park ticket and instead load up on the after-hours and party tickets. Just something to consider...
They just started doing Disney After Dark events at Disneyland this past year. All of them have a special theme and include photo ops, exclusive food and character meets, and entertainment (fireworks, dance parties), etc. And almost every ride ends up being a walk-on, because so many people are there for the other entertainment, not necessarily the rides.
First one was a Throwback night, so themed all around the 50s. I saw photos and it looked fun, lots of people in 50s attire dancing (they encourage themed outfits). Then they did Star Wars, which sold out so quickly they later added another night the following week. I did the second one and it was super fun - lots of exclusive characters that have never been in the parks (characters and droids from the Star Wars Rebels show, ewoks, etc), lots of fun food and photo spots. Awesome SW fireworks (I liked it more than the version at DHS), and even Ray Park (Darth Maul) came out and did Jedi Training for everyone, not just kids! I still sucked at it, but it was fun to try!
In the next couple months they are doing Sweetheart night (Valentines day), and 90s night. Both are already sold out. I have a ticket to 90s night and can't wait!
I'd think if MK did some of these things, it could be so much fun and worthwhile! I think it helps that it is a one-time only event, so anyone who wants to go, buys ticket for the same night, rather than spread out over the whole season.
