Is there a place to shower and change after your trip

Showers and restrooms on boardwalk before heading down to boat

on the island there is outdoor showers for rinsing before getting back on the boat as you come on the boardwalk , i think they had restrooms too but not sure .

After trip? There are hotels everywhere. You can go to Jones park and use rest room. Some of the peer restroom areas have out side showers .

There are public restrooms where you can change but I can't recall about showers.
