I use this app all the time to discover and book tours, but it could be even better through a few engineering upgrades. First, is there a way to include a minimum number when filtering by ratings? Rationale: it’s great to see a 5-star review but I’m less confident if there are only 1-2 reviews total. Second, and more importantly, is there a way to share booking details between Viator accounts? For example, I’d like to share bookings with my wife so she also sees them in her app. Thank you.

This app is really getting on my nerves as of lately. It used to be awesome. Now I can’t retrieve bookings at all. I get emails about them but when I click on the activity the interface is lacking and it’s not updated. I’ve been wasting hours now trying to cancel a tour and book another. Started a chat and their best advice was to erase the app and download again (didn’t work). Same issues on iPad. So it’s them; not me. Also, their tours are more expensive than going straight to the vendor and as some people have mentioned, some of them are scammers and Viator doesn’t care about vetting them so you are really on your own.

I booked a 9:00 AM Colosseum tour through Viator months in advance, received a confirmation email, and showed up early as instructed. When we arrived, we were told the tour had already taken place at 8:00 AM. They claimed they contacted me, but they never had my phone number. It seems they overbooked the 9:00 AM tour and quietly moved us to 8:00 without our knowledge. I booked 9:00 AM because it fit into our itinerary. We were denied access to the tour group, handed basic entry tickets, and told to run to the entrance in the rain. Once inside, the tour guide had a literal Colosseum guard assigned to keep us physically far enough away that we couldn’t hear the group. The guard even told us “scams happen a lot in Rome” and seemed genuinely sympathetic, saying this happens more than it should.
