It’s easy to park close to the pier?

Yes, it is easy to park near the pier or a little way off and you are walking along a path along the beach towards the pier

We found a parking garage that was really close to the pier for 30$ for the whole day but it gets cheaper later in the day.

Yes and no. Sometimes you get lucky and get a spot on the pier. If not you only have to walk a little. Or ride one of those scooters

Hi. I did it on the right side of the dock. The price is 15 dollars. But they told me that on the left side it's cheaper, but I did not know how to get there.

I wouldn't say it's easy to park close to the pier. but you can park real close
