Hard ticket pick up & to park hop or not

I’m debating purchasing my tickets through Ares travel or the Disneyland website. For ares it looks like I have to go to a ticket window to get my hard tickets. If I’m staying on property cab I do this at my hotel? I’d like to avoid that stop on our first morning. I’m thinking it might be easier/smoother for me to get my hard tickets through the Disneyland website. Also, I’m torn between park hopper or not. We are going 3 days and I think our second day would be the one we would hop if we had the option (want to go to DCA but the crowd level is a 9 where DL is a 3, but want to let my boys 4&6 go to Carsland before our last day so we can repeat if they love it)
