We used the arrival service for a 1 p.m. arrival on a Friday in October and I felt like it was well worth it. The lines were all the way to the back of the immigration hall and we walked straight to the front of the line. The luggage was coming out just as we got to the luggage carousel. Our private ride didn't turn out to be private and we had to wait about 20 minutes for people that came in on an earlier flight. They said they waited about an hour and a half.

I did a lot of research on flightstats.com to see how many flights were arriving on Friday's at 1 p.m. prior to our trip. I would also check out the MBJ airport arrivals webpage on Fridays prior to our trip.
