How a private request for travel costs works
What should people see first? The booking confirmation, or the fares and the hotel you priced. The dates and the cost are on it, so the request explains itself.
Can I say why in my own words? Yes: who you are going to see and why it matters, with a video if speaking is easier than writing.
Will they need an account to give? No. Each person pays by card as a guest and is emailed a receipt.
Whose account does it go to? Yours. Stripe verifies who you are, and the payouts from your request go only to you. Once your bank is connected, each contribution reaches it in 2-3 business days, no goal required first, and contributions are still accepted past the goal.
Can I tell them how it went? Record a video update while you are there or once you are home. Everyone who contributed finds it in their email, along with the people you first reached that way.
How big a goal makes sense? Requests start at $500: a goal for the whole trip, the flight, the nights nearby and the meals, shared by the people who would want you there.
