Okay, I need help ASAP so I can schedule. I know this sounds dumb, but I want to make SURE I do it right! Leaving Sat. 9/24-arrival at ship 10-10:30. I should take the test Thursday BUT 1st appt. is 11:45. This is technically LESS than 2 days. Do they count the HOURS or just the DAYS? Can I make 11:45 Thursday??? TIA
