Technology · Guest Requests

Three options.
One actually works.

Letting guests request their car from their phone is clearly the future. But the channel you choose decides whether that future actually happens - or stalls at 'please download our app.'

The test that matters

A valet guest is the hardest kind of user: one-time and impatient.

They're standing on a curb, often for the only time. They will not create an account, download an app, or learn an interface. Whatever you ask them to do has to work in the next ten seconds, cold, on the first try. Judge every option against that.

The contenders

How the three channels actually stack up

01

The mobile app

Powerful for repeat users - and a wall for everyone else. The download is where most guests quit.

Mobile app

High friction
  • Rich features for regulars
  • Push notifications
  • Requires a download
  • Account creation on the curb
  • Most one-time guests never finish

Reality

Adoption
  • Works for the 5% who download
  • The other 95% wait at the stand

An app is great for the guest who comes every day. A hotel guest who comes once will never install it.

02

The QR code

No download, which is a real step up - but it still asks the guest to find, scan, and trust a code, and it falls apart the moment they walk away from the sign.

QR code

Medium friction
  • No app download
  • Cheap to print
  • Guest must scan something
  • Useless once they leave the sign
  • No way to reach them proactively

The gap

One-way
  • You can't text them an update
  • No record of who's who

A QR code is a doorway, not a thread. Once the guest is in the elevator, the doorway is gone.

03

The text message

The winner

Everyone already has it, everyone knows how to use it, and it works both ways. The guest gets a link the moment their car is parked - and that thread stays open the whole visit.

One link from drop-off to handoff: pay, tip, validate, and request the car - branded as your venue, no install, nothing to scan.

Where Valletto changes the math

We built Valletto on the text message - on purpose.

It's the only channel that meets a one-time, impatient guest exactly where they already are. The guest gets a branded link the second their car is parked, and from that one thread they handle everything, with no app and nothing to scan.

The takeaway: the best technology for vehicle requests isn't the most advanced one - it's the one your guest will actually use without thinking. For a curbside guest who wants their car and nothing else, that's a text.
