Having orienteered in these areas, the key factor here will not be running speed, but simplification, map reading skills and limiting mistakes as much as possible.
As Gswede says, visibility is very limited, you can be 5m from the control and not see it if you are on the other side of a juniper bush strip. Relocation can be a nightmare as well because there are very few definitive landforms or larger distinctive vegetation boundaries. Don't forget that contour interval on these maps is 2.5m and not 5m. I am not sure about the US - in the UK we have some sand dune areas that are somewhat similar but not nearly as complex.
I know it is far but if someone fancies a trip then there is usually an autumn and a spring multi-day international competition organised in this same area (I suspect not the exact same maps due to the embargo) which is highly recommended to come to, the flight might be very costly from the US, but Hungary is not that expensive so you can get some quality training in visiting these comps. Especially in case someone is already over in Europe - there are lots of budget airlines flying to Hungary.

Lots of photos as well from previous years so you can get a feel for the area.
Future dates are not yet published and in my recent experience they were quite late getting it out there but usually the autumn event is mid November (recent years' dates: 12-13 Nov, 14-15 Nov, 15-16 Nov, 16-17 Nov, 17-18 Nov, 19-20 Nov etc.) and the Spring event is beginning of March (recent years: 4-5 Mar, 27-28 Feb, 1-2 Mar, 2-3 Mar, 3-4 Mar, 26-27 Feb etc.). You can see the trend, pretty consistent, so very likely it will be something similar this November and next March. That means at least two opportunities for people to come and experience the terrain - although not the heat as EricW mentioned. IMHO, one of the most enjoyable terrains for orienteering if you like to challenge your brain. I am told that it is a similar challenge to some of the France terrains where the "mazes" are partially the rock formations - here it is sand dunes and juniper bushes.
Here is also a headcam video of a race in that terrain: https://www.youtube.com/watch?v=O0AdycCJd_I
