Just take an uber. This shuttle service is awful.
The shuttle from the airport to hotel took forever, stopping at 5 hotels before ours and we had to wait 15 minutes at the curb while inhaling massive amounts of car exhaust. Total time was an hour.
On the way to the airport, the shuttle was over 45 minutes late (after our scheduled time) so we ditched the shuttle and took an uber so we wouldn't have to worry about missing our flight.
Uber - Less $, less time, more convenient, no tips expected.
Showtime - More $, takes forever, tips expected.
Uber wins.
