Didn't spring break just end? I know Easter is coming, but it is late this year. They aren't showing Fantasmic every night so I'm thinking they aren't anticipating the crowds that they had during March spring breaks. I assumed they paused MK sales because of the hype around Shadows of Memory & the 70th.
Most of the Orange County districts had theirs over the last couple of weeks, but the next three weeks are the biggest Spring Breaks in the L.A. metro. In particular, LAUSD has theirs the week of the 14th.
All of the theme parks are open during the week for the next three weeks - Magic Mountain would normally be closed during the week, for example - and Knott's is open late during the week.
The next three weeks are Tier 3-5 during the week (they were mostly Tier 2-3 recently), and everything but Inspire is blocked out the week of the 14th.
I'm always suspicious any time DLR stops MK sales right before a big day-ticket season - which the next three weeks would be. I might be guessing, but it always feels like they don't want people upgrading into MKs during the busier day-ticket seasons, since that would technically be a discount (in a weird sense, since they're the most-expensive tickets). They
really don't want people upgrading into blocked-out passes, but that would be the week after next, not this coming week.
My only guesses as to why they're not doing fireworks or Fantasmic during the week is that local schools are in session - maybe noise issues for the former and staffing issues for the latter - or that they're not expecting crowds to stay late for whatever reason. Either way, I'm surprised that they're not.
