How did Branson Landing Management Calculate 1,000,000 People?

The Branson Landing reported recently that a million people have visited the .... well, can we call it an outdoor mall yet? T

he number was based off the following assumptions:
1. 1/3 of the parking is in the parking garage
2. Average Elevator Ridership of 3 passengers

The elevator moving from the parking garage to the groundfloor of the landing occured over 333,000 times thus the number over 1 million tourists.

It's been reported from Branson Landing management that MODOT calculates roundabout traffic at 20,000 cars daily - which is the same average number of cars on the Branson Strip.
