I was especially impressed by the way AVIORA handled transitions between cities. Moving around China can be one of the least enjoyable parts of a trip if it is poorly organised.
In our case, the transfers were clearly planned, the private vehicle took much of the stress out of the process and we always knew what was happening next.
The hotels also helped because they consistently gave us somewhere comfortable to recover.
By the middle of the trip, we stopped thinking about logistics completely. That's probably the strongest endorsement I can give.
A lot of travel companies focus on the attractions. AVIORA paid equal attention to the spaces between them, which is where a lot of the real fatigue usually comes from.
