Frequently Asked Questions
For a local Saturday spring wedding, send 295 invitations to fill 250 seats. The reliable range is 278–313. Build in a firm RSVP deadline 4 weeks out so your caterer gets accurate headcount in time.
iDoTogether gives each household a personal link. Guests click it, submit their RSVP, address, and meal choice in under 60 seconds. Your dashboard shows confirmed, declined, and pending counts in real time, with no spreadsheet and no manual follow up routing.
On average, 15-20% of invited guests decline a local wedding. For destination weddings, the decline rate jumps to 30-40%. Factors like day of the week, season, and travel distance all affect the final number. Saturday weddings see the highest attendance, while weekday ceremonies can see decline rates as high as 30%.
The average wedding drop-off rate is about 15% for local weddings held on a Saturday. This means if you invite 100 guests, roughly 128 will attend. Destination weddings have a much higher drop-off rate of around 35%, meaning only 98 out of 100 would attend. These are industry averages — your actual numbers will depend on your specific guest demographics.
It depends on your wedding type. For a local Saturday wedding, you can safely invite 15-20% more guests than your venue capacity. For a destination wedding, you may be able to invite 50-55% more. Use the 'Fill My Venue' mode above to find the right invite count for your venue size.
Season plays a meaningful role. Spring and fall weddings tend to see the highest turnout due to comfortable weather and fewer travel conflicts. Summer weddings (especially July/August) can see 3-5% lower attendance due to vacation conflicts. Winter weddings often see 5-8% lower attendance due to weather and holiday scheduling.
Friday weddings perform much closer to Saturday than Sunday does. Many guests are already in a weekend mindset, and taking one day off from work is more manageable than losing a Sunday evening before the work week. Sunday weddings consistently show higher decline rates because guests need to be back at work Monday morning.
The biggest bottleneck is chasing people who ignore paper mail. iDoTogether lets you text each guest a personal link. They tap it, RSVP, and submit their meal choice in under 60 seconds. Couples using our software typically collect 80% of RSVPs within the first week.
Send RSVP requests 6-8 weeks before your wedding date. Follow up with non-responders at the 4-week mark. (Pro-tip: If you use iDoTogether, your dashboard automatically flags exactly who hasn't answered, so you don't have to manually cross-reference a spreadsheet).

Filling a 250 Seat Venue?
Filling a 250 seat venue requires sending approximately 295 invitations for a local Saturday spring wedding. At this size, over invitation is a necessity, not a strategy. You simply cannot expect 250 specific people to say yes without giving yourself a buffer. The attendance prediction is reliable (85% for local Saturday), but managing 295 invitation responses is a genuine logistics challenge. You'll need a system that tracks both "yes" and "no" responses separately from "no response yet." That third category is the one that causes caterer headaches.
To fill 250 seats, you need {inviteTarget} people to respond to invitations. That's a real coordination problem. iDoTogether tracks every household in real time and flags the "no response yet" group automatically so you know exactly who still needs a nudge.
