4/5
If there is no trusted person or relative to accompany you, they require a companion and a driver. I could use LYFT for round trip, but I don’t know why I must hire a stranger to be my companion. What does Summt expect them to do? If an emergency I assume staff would handle it, not the companion. Then the office changes the time so I keep guessing when I need to be picked up.
