You can still create a memorable surprise party without breaking the bank. Consider options like a potluck dinner where guests bring dishes to share, hosting a movie night at home, or organizing a DIY game night with board games you already own.

Q: How can I involve the birthday person in planning without giving away the surprise?

You can involve the birthday person in planning by asking them subtle questions about their preferences or interests. For instance, you can inquire about their favourite colours, hobbies, or dream celebrations without revealing your intentions. Use their input to guide your party planning.
