I recently purchased show tickets through TripAdvisor's subsidiary Viator. I mistakenly chose the wrong date - a week earlier than we would be in town. I did not realize this until after the original show date. I asked if I could transfer the reservation and was told I couldn't and was berated for not noticing within the policy 24-hour period. I understand policy and if I was trying to cancel it would be different - I still wanted the tickets, just on a different date. I don't recommend booking any entertainment through this site. Out the money and no show tickets.
