2–3 Weeks Before The Party

  • Choose your mission plan.

    Choose your space party direction, guest count, and party setup so the rest of the plan feels easy.

    Send invitations early and make a short list of the supplies, serving pieces, and activity materials you still need.

  • Order the big essentials first.

    Place orders for your space party decorations, tableware, balloons, and party favors while you still have time.

    If you are using custom pieces, leave a little extra time for shipping and any last-minute swaps.

  • Lay out your galaxy party setup.

    Sketch out where guests will eat, play, and take photos so setup feels intentional instead of rushed.

    Decide which focal areas need the most attention, like the food table, entry, or favor station.

1 Week Before The Party

  • Check your guest list and party inventory.

    Confirm your headcount and send a quick reminder so parents know the time, location, and any outfit notes.

    Double-check that all shipments arrived and make a short backup list for anything missing.

  • Finalize your space activities.

    Pick a few themed moments like astronaut training, a moon walk game, or a planet craft.

    Set aside supplies for any launch-themed activities, table crafts, or simple party challenges.

  • Plan cake, snacks, and take-home favors.

    Order the cake or dessert, finalize snacks and drinks, and make sure serving supplies are ready.

    Set aside favors and any space party extras now so you are not sorting them the day of.

1–2 Days Before

  • Pre-build the main launch zones.

    Pre-sort decorations by zone and label bins or bags so setup goes faster.

    Assemble simple elements ahead of time, like favor bags, signage, or tabletop pieces.

  • Prep for a smooth party flow.

    Charge devices, print anything you need, and set aside scissors, tape, extension cords, and cleanup supplies.

    Walk through the event from guest arrival to pickup so you know where transitions may need a little help.

  • Make the last stretch feel low-stress.

    Pick up fresh food items, clear party surfaces, and leave yourself a little buffer time before guests arrive.
