Seasonal Party FAQs

How do I plan an outdoor summer birthday party?

Key elements: shade structures, plenty of water/drinks, sunscreen station, water activities (sprinklers, pools), and a rain backup plan. Start 2-3 hours before sunset for ideal temperatures. Serve cold foods and frozen treats.

What are good winter birthday party activities?

Indoor activities: movie marathon, craft stations, baking party, scavenger hunts. Outdoor activities: snowman building contests, sledding, ice skating. Keep warm drinks (cocoa, cider) flowing and have cozy seating areas.

How do I combine Halloween and a birthday party?

Lean into the spooky fun! Costume party with contests, pumpkin decorating, monster mash dance party, spooky snacks. Use "birthday zombie" or "birthday witch" themes. Ensure activities work for non-costume guests too.
