The process.
Get in line PRIOR to park opening, then head Straight to the Hyperion Theater (home of Frozen) as quickly as possible and find the line.
Cast Members actually hand out the passes, but will allow only one person in a group to get in line IF they have everyone's tickets.
As for stand by, do they allow it, the answer is yes, does it work, in reality no, there are very few open seats after those with passes are seated. So maybe 100 people in line get in, the last show tends to be the best, as more folks miss the return time on their FastPass due to doing other things, but it is still a very low number. Most stand by people wait around 2 hours, maybe a bit less.
One good thing, the Frozen FP (along with the World of Color one issued next to Grizzly River Run) don't count against being able to get a new one.
So have the entire group enter the park before opening, pick someone to be the "runner" and give them your tickets, the rest can go grab breakfast in the opened area before rope drop, basically coffee and pastries.
The runner goes to the east side of rope drop and finds the Frozen queue. Then head to "A Bug's Life" where the Radiator Springs Racers FP's are issued. Note the time printed to plan to get another "attraction" FP, and then Grizzly River Run for the World of Color FP. Then head back to your group and hook back up.
