Is 7 days parking is considered short term ? How much does it cost to park in the garage ?

Seven days is long term. Plus, if you're going to be gone seven days, long term parking is cheaper.

Long term, honey

I parked in Long term for 4days. It's cheaper

I believe 1 day max is $18 in short term; $11 max in long term. There's a shuttle that will take you from the terminal to long term (actually to your car). The only real differences are that ST is close to the terminal and you must walk there + most of ST is covered. LT is uncovered parking and you typically take the shuttle, although it's walkable.
