Is it easy to find parking spots in the area? Or should I choose the Tennis Garden line, for being a park and ride location and a just a couple of miles further from where I'm staying (Rancho Mirage)?

First time using the shuttle service or even taking my car. I used to stay in La Quinta and ride my bike to the festival.

Many thanks in advance!

Ps. It really doesn't have to be free parking. Paid and honest price parking works too!
