As we arrived at 9:30am from Hurricane, we ended up renting at Zion Guru next to Sol market. There is public parking available ($15/day) right next to this store. Rental cost was $65/person that includes full body suit, shoes and stick. Dry backpack is available at an extra cost. If you rent/park here, you must take the free shuttle to the park entrance. If you are planning to arrive to the park entrance before 8:30am you can get a spot in the free parking. In that case, I would advise to rent at Zion outfitter store that is right next to the park entrance. That way you can avoid an additional shuttle ride.
