I love how optimistic everyone here is about getting a Boarding Group! Just wake up the family at 4 am, get on the freeway by 5 am, get to the front gate at 6 am, and you'are almost guaranteed a Boarding Group for 8pm that night!
That said, I think we are underestimating how few people per day are being allowed to get a Boarding Group reservation. It's a tiny minority of the daily attendance. From reading and monitoring the insanely detailed thread over on the DHS forum for the last month, several respectable insiders and smartniks have come up with the following figures;
Max Hourly Capacity of Resistance Ride = 1500 riders per hour (slightly less than Radiator Racers, or about half of Pirates)
Current Hourly Capacity of Resistance Ride = 1000 riders per hour (purposely running fewer cars than designed to improve overall reliability and shorten downtimes when they do happen)
Current Hourly Boarding Groups Distribution = 800 riders per hour (to accommodate for regular daily breakdowns)
So let's just assume they will start out the same way at Disneyland and run it like that for at least the first month or three. 800 Boarding Group reservations per hour over a 16 hour operating day (8am to Midnight) is 14,800 Boarding Group ressies per day.
But let's just go
super optimistic and say they give out 15,000 Boarding Group ressies each day at Disneyland.
15,000 people is nothing. That's the amount of tourists staying in only 25% of the 25,000 hotel rooms in the Anaheim Resort District. 15,000 is the amount of people who can park each day in just the 6,500 new parking spaces of the Pixar Pals Structure, assuming 2.5 people per car. 15,000 is about 18% of the daily Resort attendance on the average Saturday with 85,000 people in both parks, or 15% of the daily Resort attendance on the average busy holiday with 100,000 people in both parks.
15,000 riders per day is a ridiculously small fraction of the daily paid customers. 
Sure, the tourists staying nearby will learn to set their alarms and storm the gates each morning at 7am, and the childless AP's will relive their college days and pull an all-nighter to be at the parking structure at 5am. But even a big chunk of those two demographics still might not get a Boarding Group if they stop at the Downtown Disney Starbucks.
I mention this not because I am worried about any of us here in this thread, we'll set our alarms for 4am and figure it out like we always do. But I mention this because I think this is going to be a very rude awakening for the vast population of Southern California, or any tourist who isn't leaving their hotel room on their expensive vacation by 6am. There will be a lot of disappointment this winter and spring.
This Resistance ride Boarding Group process is going to rewrite the playbook on how people use Disneyland as a leisure destination. Expect rants and tears and a new round of lawsuits from the SoCal DAS community.
