iirc, the TÜV had some issues with the main entrance to the hotel through the loop. For some reason, it doesn't fulfill all the requirements to serve as a proper emergency exit, so in case of a fire, hotel guests would have to be evacuated through a different entrance than the one they came in through, which generally requires legitimate exit routes to have higher capacities than normal, require extra signage for guests and firefighters, and all around it would have been a hassle to do all of this within the limitations of an almost entirely done hotel.
Now once that decision is made, there is no turning back from that. It's sort of a reverse grandfathering. From my experience, TÜV is generally all over the place, and an ill-tempered inspector can make or break your design.
EDIT: actually, scratch that fire argument, of course the hotel has enough rescue pathways to evacuate guests in a fire. However, TÜV deemed that the bridge through the loop was not viable for any sort of evacuation, especially because it spills out into another "facility" with rough terrain (aka Deep in Africa) which is inaccessible for ambulances. Apparently that is such a big deal that the park scrapped that entrance entirely.
