How this score is calculated

This score is based on one provider. GetYourGuide rates it 4.82 from 188 reviews. We place that rating among all GetYourGuide ratings and weight it by its review count. If the tour is found on another provider later, both ratings are combined.

How the score works and rating distribution in San Antonio
  • Each provider rating is turned into a percentile: the share of that provider's ratings it beats, weighted by review counts.
  • Listings on different providers are combined in proportion to their review counts.
  • Tours with few reviews are pulled toward the average until more reviews come in, so a handful of perfect reviews can't top the list.
  • The result is shown from 0 to 10: this tour scores 9.0. Top 3% in San Antonio means it ranks in the top 3% of tours in San Antonio by this score.
