The other option people forget about is to sleep at normal time (or earlier if you’re careful) and just wake up before the fights you’re looking to watch.
I’ve hosted quite a lot of get togethers at mine for UFC and boxing events and the pattern that’s worked for us is basically chill in the evening then kip from around 12/1 till the co-main. That’s a calm 3 hours nap.
It doesn’t slaughter the work week if you get some sleep in there. Just the event being live adds a lot to the night.
