19 days and counting! We're excited about our first trip to Couples.

We're going to CN on 4/16 and have a couple(s) questions.

1) We booked directly through Couples and were assigned a flight that arrives at Sangster International Airport at 7:41 PM. What type of traffic conditions do you usually find at that hour on a Friday and what is the normal drive time to CN at that time of day?

2) We probably won't arrive at CN much before 11 PM that night. How does late check-in work?

3) Our return flight is scheduled to depart 8 days later at 8:13 AM from Sangster. How early do the airport shuttles start running from CN? I would assume the traffic is not too heavy at that hour on a Saturday morning. I don't know how much time to allow for check-in and customs. Would the local shuttle (Tim Air?) be a better option?

Thanks in advance for your help. This message board seems to be the place to go for ALL the details.
