All-in means taxes and fees as each site reported them to Google Hotels; a resort or destination fee may be extra. Each row is that site's lowest listing. Hotel's own site is the seller Google Hotels lists under the hotel's name. The snapshot kept up to 28 listings per hotel, so sites priced above these may be missing.
