A pretty decent episode to go out on. I'd even say it does the "wacky" episode type better than the 100th episode. It's good to have at least a little grounding in seriousness.
One nitpick: They could probably have avoided reiterating that the Tantabus was going to escape the Matrix and do stuff in the real world about six times. It feels like they meant for those reminders to constantly stab Luna in the heart, but half the time she wasn't even in frame when it was brought up.
The animators really went wild on this one.

Twilight gets the princess bed.

Luna's room has: wacky egg-moon bed, stalagmite-ish lights, an odd alarm clock, pony slippers

Have we ever seen this pony before?
