Have you considered rolling admissions now that you're in Cali all year? Those that aren't ready for demo day could wait till the next one. You could have 3 or 4 demo days yearly. That would solve scheduling problems.
It might also make the application process easier on you by trickling in the applications. No cramming to get to them all. You could still do batch interviews monthly.
1) You are already interested in them, and would have interviewed them anyway
2) They have other offers on the table with early deadlines, particularly mid or late April obligations
