We parked in the lot across from 4 Points Sheridan with no problems. The parking lot attached to the sports bar we were told you can also park. The bartender said pre covid they charged a minimum to park there overnight yet post covid you can park there for free. Closest bathroom is across the parking lot at a 24 hour Walgreens ,yet its only courtesy to purchase something if your going to do that. We found a beach front parking lot just 2 blocks away that had bathrooms and 2 portapotties that we were told we could park at.

Slept in parking lot south of Margaritaville. Noisy on the weekend. No public bathrooms that I found. Cold beach shower. Decent for a place to sleep but far from ideal.

Great stay. public bathroom opens and close at 7am and pm.

Stayed here last night (Wednesday). Arrived around 9:30 pm. Walked to beach and back. Porta potty in lot but it was padlocked. Used bathroom in Sneakers restaurant/bar before they closed. Quiet night. Not disturbed. Parking lot security was in lot next morning and hung out behind my van for a bit but never bothered me.
