UBER is not reliable company for transport! Arrived too late for concert. Promised by rideshare that latest arrival time for concert in Boston would be 7:39 for 8:00 show - two tickets for show purchased months earlier. It was already 8:02 and had to pay driver extra $ to drop me closer to concert hall. I finally arrived late- and had to wait for break to enter show-missed 1/3 of performance.
