Stuff the trains AND the buses.
You can bet that even if they put on the buses,
they will probably charge a minimum of about
$10.00 per person.
I would rather pay $14.00 or $15.00 in advance
for a ticket to park the car. That covers 4 or 5
people, depending on how many you can fit in
your car, adn you will get there and home again
in half the time that it takes for the bus.
