I'm looking forward to seeing it in action but I don't expect the "OMG, I have to transfer" experience to be that bad. You're not going down and back up stairs. You're not going from one end of a bus terminal or airport terminal to another.
Get off one loop and it's a short walk to the next loop. With continuous loading too, it probably won't be too bad either for crowding up. What remains to be seen is how people-traffic will be guided inside the station. There will theoretically be X-traffic between people coming from Pop/AoA heading to DHS and people coming from DHS heading to CBR exit or Riviera/Epcot, so I don't know if CMs will be directing people or if it'll just work out that traffic heading to DHS and traffic leaving DHS won't peak at the same time.
[Edit]Found an angle where you can see in the station / how close the gondola loops are:
