is there long term parking avalible? 24 to 38 hrs?

Yes

I believe only available long term parking is in parking garages,

I don't sure .

Here is a secret. After 10pm they leave the door for the car open so you can park in the parking garage accross the street for free. That is as long as you come and leave on days after 10:00pm

There is a parking ramp with a $. And there is metered parking on the street.

Yes accross the street; $7.50/day

No it is metered parking only

Don't think so

Not at their terminals
