Is there a way to go there if you don't have a car? Is having to drive and parking required to go? No walking entrance?

Uber/lyft. I thought about uber from downtown but opted for rental car on my recent trip.

There's a drop off lane for people who don't want to pay to get into the parking lot, it's to the left of the main entrance. You can also walk along the right hand side up into the parking lot, just be careful! There's not a lot of nearby parking for this area, so you'll be walking a little bit but the parking is 25$ for a day so it's easier to lyft from it hotel/a nearby area for 10-15$.

Not sure about now, but pre-covid you could walk to the gate (lots of car traffic, just be careful!), but it's probably your best bet to get dropped off up front.

You can get dropped off and walk up to the gate!
