Quick Tips for Planning A Party

To have a magical mermaid extravaganza, the success is all in the planning and organization details. Have you ever been to a disorganized party? Ran out of food? Needed more space? Got bored after 30 minutes? Weather was horrible? You don't want this happening to you, so here are some quick tips on planning a party your guests will talk about for the rest of the year.

  • Set a budget!
  • Determine the guest list
  • Choose a suitable date and start + end time
  • Choose a location that can accommodate your guest list comfortably
  • Figure our food and drink details (are you just serving snacks, finger foods, having a buffet, hiring a chef?)
  • Create and send invitations (doesn't hurt to have a spot on the invitation for allergy information or food preference like vegan or pescetarian)
  • ALWAYS ask for RSVPs (this helps with getting a good estimate of how many people to expect and accommodate)
  • Music (are you hiring a DJ or playing a set playlist?)
  • Gather decorations
  • Plan to host some activities/games
  • Have a clean up plan!
