My buddy and I are planning a trip to LA for a week, and for one of those days, we want to go to Universal for Halloween Horror Nights, and the other, we want to go to Magic Mountain. Both of us want to be home before October 31st (can't miss Halloween at home!) but we were thinking of taking the trip maybe the third week of October. I've only ever done either Magic Mountain or Halloween Horror Nights once a piece, so I'm not too familiar with either of them, especially in October. It's been literally 11+ years. So I'm just wondering how long the Horror Nights event lasts for? Like, does it start on October 1st and go all the way through the 31st? Are there better or worse days to go during this time (Such as Tuesday vs Friday)? How packed does it get? What time does the park usually open in the morning in October? What time does it close at the end of the night? Is there a designation of when regular Universal closes and Horror Nights begins? Do you have to pay extra to be in the park during Horror Night hours? How are the crowds? And how much extra is the 1 Day Express Pass over a regular pass? As for Magic Mountain, we just want to go there to ride some extreme coasters. How is this place during October? How are the crowds? Any idea about what time the park opens and closes? Thanks!
