Yes. Would you rather install a full-on app for a once-off event (concert, festival or conference) or would you rather just install a light-weight PWA or just use the website?
And that’s not what most people consider a PWA.
Any app that's geared towards visitors or tourists is better served as a PWA - think of the apps used to pay for transit, or parking in a city you're visiting. A website is Ok, but offline access and a shortcut on the homescreen would be better.
