This way please, “oh look we have photos of you, would you like to buy one?”
It’s the last and final gasp to grab some value from you after a tourist adventure or visiting a destination, it’s a way for you to remember. It’s also when your most likely to grab something that symbolises that event.
The gift shop shouldn’t ever be the last we hear from you!
What about post event? 6 months later? There’s a market there. Getting permission and having an ongoing conversation with those that visit. Getting them on board and reminding them of the good times, sharing with their friends, sending them a note at christmas saying hey we could send a photo direct to your relatives.
