We're going to have my MIL and FIL with us for 2 days at the theme parks and my MIL will be in a wheelchair. If she is not actually going on a specific ride but all of the rest of us are -- do we have to go into the regular line or can we go in the wheelchair accessible line and she can wait for us? She will go on some rides but not all and my FIL and the rest of us will go on more than her.
