Yes if you survive on friday you get Saturday off. Technically you can fire another bullet then and take the highest stack through but that's a complete waste of money in most cases. Could take that day to play some GTO live cash games
Idk if they still do community freerolls for the uk tour, they used to be on Sunday a few hours into day 2, sometimes earlier sometimes later, plenty of time to bust the main in case it happens.
Yep as NMP says you get the day off. Fri looks like a late finish to me so you will be thankful for it! Meet and greet, go snowboarding or 'sky diving' right by the casino or just relax and soak in the atmosphere with a beer and watch the mighty Wolves knock out Man Utd in the cup
