There is an additional parking lot for guests at the entrance. I do not believe guests are allowed to park at the actual campsite. Curphew is 10pm. Absolutely NO alcohol. Some- one once told me it's supposed to be max 4 adults, 4 kids, 4 pets. However, I think that is just for the nite-- not for guests (but don't quote me). Here is the link if you would like more info: https://www.reserveamerica.com/explore/massasoit-state-park/MA/32611/overview
A guest pass can be purchased for $8 at the entrance of the park for visitors to your campsite and they can stay until 8pm. If you're camping, you're allowed 2 vehicles on your site.
