Frequently asked questions

How do I know how much food and drink to prepare?

Use an RSVP tool to get a firm headcount. Assume 70-80% of RSVPs will actually attend. For alcohol, plan 3-4 drinks per person for a 3-hour gathering. For food, prep for your RSVP number plus 1-2 extras. Who's In locks your guest list so you know exactly how many to cater for.

How do I manage plus-ones without losing control of my guest list?

Set the rule upfront in your RSVP: "You are invited plus one. Please name your plus-one in the RSVP form." This prevents surprise additions and keeps you in control. Send the link 2-3 weeks ahead and close it one week before the party.

What's the ideal time to send house party invites?

For casual weekend parties, send 2 weeks ahead. For big bashes (20+ people), go 3-4 weeks. For themed or special events, 4-6 weeks gives people time to commit and prepare costumes or dishes. Close RSVPs 1 week before so you know final numbers.

How do I handle RSVPs when people flake at the last minute?

Send a reminder 48 hours before the party asking for final confirmation — this catches people who'll definitely come. For student parties, consider a small deposit (£2-5) per RSVP to ensure genuine commitment. Always overprepare slightly for food and drinks in case flakers show up anyway.

How do I manage parking for a house party?

Ask guests how they're arriving in your RSVP form. If parking is tight, assign specific spots in your invite or give clear guidance on where to park. For larger parties, mention nearby street parking or train links upfront. Limited parking is a good reason to cap your guest list.
