Better to call the restaurant They can help you
I have no idea where you're going to find RV parking near the restaurant.
Nothing close.But they are available
I agree with Mike P. parking will be really hard to find for a RV.
RV parking will be incredibly difficult to find. Log Haven has mandatory valet parking (especially for events like a wedding) due to the lack of parking up there. Millcreek Canyon is narrow and cuts through a neighbirhood. You could park at the Olympus Hills Shopping Center (Dan's Market) and take a taxi, Uber, Lyft, or carpool with family/friends of the bride and groom.
Find one in the valley and ride share up.
