I attended a group trip to inner mongolia during the first week of october, organized by Wanna Travel.
This organisation sold a busy and very attractive itinerary.
In the end only half of what they sold was delivered.
One week before departure, once they got the money, they communicated a new schedule, which was already a reduced version of what they sold.
During the trip that new schedule was not followed either.
The largest part of this trip consisted out of free time.
Such a missed oportunity
If you want to feel ripped off, I can recommend this organization.
Otherwhise, look for a different one.
