Tips for a great park party

  • Doublecheck the park website a few days before your event to make sure everything is open for business as usual.
  • Go to the park early, at least an hour ahead of the party start time, and stake out a table if you didn’t reserve a shelter. Mark your spot with a plastic tablecloth or balloons. Bring a big blanket or two in case you end up on the grass.
  • Be sure to have a way to cover food so flies and other critters don’t join your party. If you’re packing perishables, bring enough ice and a cooler for safety.
  • Pack extra towels, bottled water, sunblock and bug spray, because you know that someone will forget theirs.
  • Have a backup plan in case of rain.
