PLEASE NOTE, I AM MAKING A REVIEW ABOUT BELL TRANS AIRPORT SHUTTLE TRANSFER SERVICE AND NOT PRIVATE TOURS.
Booked a round-trip shuttle from airport to vegas strip VIA viator.com which is a reliable site. On our arrival @Vegas , nobody was on the Bell Trans DEsk but only a sign stating where customers should go for further assistance. Most of the airport staff were unhelpful so we ended up with difficulty trying to find where this sign will lead us since it was our first time at vegas. Eventually found their relocated desk, after 15 mins which was rather not where the sign stated it was! However despite this disappointing start with Bells, we still used their shuttle service for airport transfer several times during our US tour and they got better with service. Drivers were on time and professional and I would recommend them as they offer good value, $7 for single roundtrip/person going to most Strip-located hotels.
