Our building has a separate main entrance and handicap access (which includes an elevator to travel between street level and lobby vertically). As we are planning to place entryway mat (6'Wx10'L) to both main entrance and the handicap access (not directly at elevator front as door swinging out is very close to the floor), we are also afraid that the one at the handicap access may cause inconvenience to some of our visitors.

Is it a must to place an entryway mat there as well?
