Do guests pick a meal when they RSVP?
Yes, that is where it belongs. When you offer meal options, each guest chooses one in the same reply as their confirmation, and can add an allergy note. Nothing separate to chase later.
What about a guest who cannot eat any option?
Leave a free-text note on the reply so they can say so. Their restriction lands on your guest list under their name, giving you time to arrange something before service rather than learning at the table.
Will I get a count per dish, not just a list of names?
The guest choices add up into a running count per option, which is the number the caterer wants. You read the figures off the list instead of tallying replies yourself.
Does it track whether someone opened the meal form?
No, and it does not need to. What you get is the answer each guest submits, meal and allergy attached to their name, and the totals that fall out of it.
Can I still change the count if plans shift?
A guest who updates their reply edits the same record, so a dish count moves with them until you hand the final number to the kitchen.
How should I word the meal question for guests?
Keep it short: name the options plainly so the labels are honest, and add one line inviting an allergy note. The reply page shows the choices beside the confirmation, so guests answer without scrolling back.
