New TripAdvisor promotion. Book any hotel on TripAdvisor and they’ll email you a 20% off code for Viator.com. If you planned to use Viator anyway this is a great deal as general use codes are sometimes hard to come by. You only need a single hotel night booking and there’s no minimum spend in the terms. The 20% off has a $250 min/$5000 max application. Take care you have to complete the booking on TripAdvisor not just click through them to another ota.
