Picture the site visit: you are standing in a dark dome, seats curving up around you, and the person showing you round gives you a figure that sounds workable until you ask what is inside it. A gender reveal planetarium budget rarely arrives broken down. The other half of the job is the secret, and that only takes one guest with a screenshot. You can build a digital invitation from the catalogue today, send it by link or QR code, and keep the reveal out of every open group chat.

Venues quote in different ways, so the figure you were handed may or may not include the person running the projector, the extra half hour, or the hall where the cake goes. Before you call anyone back, know which lines you are paying for and which ones you are not.

What a gender reveal planetarium budget actually covers

Most domes are rented as a block of time with staff attached, and the staff is where quotes drift. Ask for the breakdown in writing, line by line, and check whether set-up and pack-down minutes sit inside that block or get added on top. A celebration that runs thirty minutes long is a different invoice.

  • Dome rental: ask whether it is charged per time block, say one or two hours, or by the loose hour. It changes the final bill if the toast runs long.
  • Projection technician: confirm in writing whether that is included or billed separately, and whether the rehearsal run-through is in the same price.
  • Rooms next door: many venues rent only the projection room, so ask if the foyer is yours for the cake, the photos and the toast at no extra charge.
  • The extras that inflate the total: catering, photographer, entrance decorations and music. Get each one priced on its own line before you say yes.

Digital invitation with a QR code keeps the secret

The secret is the expensive thing to break. If the baby's name or the time of the reveal is on a poster or in an open group chat, someone lets it slip before the dome goes dark. A digital invitation travels as a link, a QR code or a message. Nobody installs an app, guests open it on their phone and confirm from the same screen.

It costs 29.99 EUR for the invitation, one payment with no subscription. The price does not move because ten more people are coming to the dome, or because you push the start time back. Change the venue, the hour or the map and you edit the invitation in place: the link stays the same and nobody has to reprint an envelope or send a fresh message around.

Confirm the slot and the seats before you sign anything

The order matters. Lock the date and the time slot first: the cake, the photographer and the decorations bend to the hour the venue gives you, not the other way round. Then the invitation, because until the link is out nobody knows which planetarium or what time to turn up. Ask how many real seats there are, children included, and whether a baby seat fits beside yours. Ask when you can get in to set up. Agree on the plan B too: what you do if the projection fails, the technician is late, or the person carrying the result gets stuck in traffic.

A planetarium is a room you can swap. An invitation that keeps the secret is the part you cannot get wrong.

If the planetarium price is too high, change the room

No dome on your budget does not mean no reveal. A ceiling projector and an inflatable dome at home do the same job, and the surprise lands just as hard. You can also keep the planetarium for a small circle and hold the bigger party afterwards in a hall or a garden, or send the invitation to everyone and print a few copies for the people who will keep them. What is worth settling before you call the venue is the invitation itself: it fixes the date, protects the secret and does not get more expensive when the guest list grows. Pick a design, test it free, and publish it the moment your slot is confirmed.
