TripAdvisor WiFi Plus is a subscription service powered by social WiFi marketing provider Captini. Restaurants that register for the service receive a hot spot that connects to their own in-house WiFi.

When guests sign in to TripAdvisor WiFi Plus with an email address or social media credentials, they see a landing page custom-branded for the restaurant and automatically receive an email after they leave encouraging them to post a review on TripAdvisor.

On average, restaurants that use TripAdvisor WiFi Plus collect 70% more reviews, TripAdvisor says.
