How many people can accompany an ECV user using a return time at Disneyland

[musicmom3331]

I’ll be at Disneyland for the 70th because I’ll be turning 70, also. With me will be my two daughters, son-in-law, and three minor grandchildren. I’ll be using an ECV. On the rides that you cannot take the ECV through the line, and you’re given a return time, how many of my family can accompany me?
Thank you!

DH and I have never run into a limit before, for these attractions, there really shouldn't be one, as you will want to ride with your entire party and there is no other way to access these attractions, but with all of the new rules, not entirely sure.
