Digital invitation for a Halloween library hunt in Lisbon

It's 17:40 and the treasure hunt starts at 18:00. One parent is walking the outside of the neighbourhood library in Lisbon, phone in hand, re-reading a message that says the children's room is on the ground floor, near the newspaper archive, ask for Marta. Two more families are doing the same loop on the other side of the building. The message said plenty. It just didn't say the thing they needed.

That is the whole argument for a Halloween digital invitation: one link with the room, the hour and a map, and you can still fix it at 17:45 without writing to thirty people. You can build one today from the catalogue and send it before the pumpkins go on the doorstep.

At 18:00 in the children's room: what the digital invitation must spell out

The editor gives you one field per detail instead of a paragraph where everything melts together: label, names, date, one sentence, place. Fill them and stop typing. There's a character counter, which quietly kills the classic children's room, ground floor, next to the newspaper archive, ask for Marta — the line nobody finishes reading on a phone. And put the venue map in the invitation: the family who has never been inside arrives without texting you at 17:40 about which door it is.

• Label it exactly what it is: Halloween Treasure Hunt at the Library. Not Sam's party.
• Pick-up time in plain text, not only on the map: the door opens at 18:00.
• A photo of the real entrance, decorated portal included, as the cover so people recognise the building from the street.
• One RSVP question that actually matters: who stays for the final story time at 19:00.

The treasure hunt starts at the library door

Scene one can be the door itself: a short line like start where the door creaks, and the pick-up time in plain sight. Break the route into three or four scenes — threshold, children's room, the book table, handing over the loot — and write one sentence each. Six- to ten-year-olds read in snatches; a paragraph is a wall. Nobody needs the full plot, they need to know where to run next.

Then add photos: up to six of your own, one marked as the cover and any of them replaceable later. A shot of the paper bats on the portal does more work than three lines about decorations. If the costume plan shifts from witches only to anything goes, you edit that line and the link stays the same, no reprint, no resending.

If a guest has to text you to ask what time it starts, the invitation isn't finished.

Halloween digital invitations in Lisbon: where to buy them and what they cost

Send The Joy sells digital invitations at 29,99 EUR, one payment and no subscription, bought and edited in the browser. You can filter the collection by style and test the cover for free before paying; when you buy, every scene unlocks. The invitation content can be set in Portuguese, Spanish, Catalan, English, French, Italian and German, which helps when half the class reads a different language at home. It's a web page of its own, not a PDF or a picture: guests open it from a link, a QR code or a message and install nothing.

Confirmations land in an ordered list inside the same invitation, so you're not copying names out of thirty separate chats, and you write the questions yourself — who stays for the story time, how many adults come with each family. If pick-up moves from 18:00 to 18:30, you change the hour and the link is still the old one: guests see the updated version. One honest catch: everyone needs a phone, tablet or computer with a connection. If a grandparent wants paper for the fridge, print two or three copies yourself and keep the link for everybody else. Set the hour, the room and the first clue, publish it, and send one link to the group.
