Conceptually Empire Vacations' 3-day tour is definitely great: covering the significant distances to visit Grand Canyon, Antelope Canyon, Bryce Canyon and Zion Canyon without needing to worry about driving and itinerary details is a significant benefit. The potential availability of guides covering multiple languages would seem to indicate good tour design.
Actual implementation of the tour, however, was somewhat mediocre. Communication was not great. Achieving booking, deposit and final payment took multiple emails. Empire Vacations did not provide any means of contacting the tour guides or for participants to be contacted, despite a reasonable assumption that almost everyone would have a mobile phone.
Throughout the tour, timing was abysmal. On all three days, toilet stops and lunch stops were much longer than necessary. A long time was also spent at a Route 66 junk gift shop and a native Indian craft shop. Consequently, the key stops at the National Parks were more rushed than needed to be the case.
The start in Las Vegas was more than an hour late. Every stop would run at least 10 or 15 minutes longer than indicated, not helped by the tour guide Janet repeatedly indicating that she did not mind people being late - so they were. The net effect was that by the time that the overnight stops were reached, any food outlets were closed or closing. There were no issues with two overnight accommodation venues.
As the main guide, Janet was friendly but the level of her trip commentary was poor. Little to no effort was made in preparation for each of the national park sites. For example, at Zion Canyon a number of the shuttle stops and tracks were closed. One would have expected the guides to consult the park website and let the tour participants know what was available and what was closed, but they failed to do this.
It was also unfortunate that the tour was undertaken with a truck type bus that was particularly prone to unpleasant vibration and noise and at times seemed to be travelling more slowly than other traffic, although there were no issues with the driver.
Despite the particularly poor running of this Empire Vacations tour, I am still giving it a "very good" rating. Each of the canyon stops were great to visit and the overall cost of the tour was worthwhile.
