Yes, you can use your hopper pass. The only thing that has changed is that you don't need to use that plus on your hopper pass until you enter a club. If you just wanted to wonder the streets and not enter a club, you wouldn't need to use your plus. Once you enter one club, your ticket is scanned and you get a wristband. I do not know if you have to continue to show your ticket at each new club, but you don't have to pay admittance at each club.
