What Disney After Hours Should I Do?

I will be in Orlando the 2nd through the 7th, for a work conference. Unfortunately I won’t be able to fit in park time during the day, but planing to do a night of after hours. The Conference is 8-5 Monday through Friday. Magic Kingdom After Hours is the 3rd 10:00- 1:00 am and Hollywood Studios is the 6th 10:00-1:00am. I would love to do both nights, but not sure i could function at the conference with two nights of going to bed around 2:00 am and getting up at 7:00am. Looking for advice on which park you would recommend if i only pick one.
