I should imagine that the second dining room demon will probably remain out of action for the rest of the season. Simply because the fact they've let such a major prop go un-resolved for so long would suggest to me that there's something seriously wrong with it, which will either cost a bit, or take a lot of time to fix.
The syncing is annoying sometimes, but I think it's probably more down to the ride system than the individual effects. Obviously, the ride cars alter their speed many times throughout the trip. This is mainly relative to both the scene they are traveling through at each moment, and to maintain the spacing clearance either side of the vehicle. It shouldn't be that much of an issue really, as when the system runs properly the speed at a set point should be fairly consistent between vehicles. However, no doubt owing to its age, it has issues where some of the vehicles are always either under or over speeding (That's why two vehicles can leave the station bumper to bumper, but can come back to offload with a 5 foot gap between them
). This not only causes a problem for that vehicle, but usually most of the other normally functioning ones too, as they all move relative to each other. In theory they aren't doing anything wrong, but for a moment each of them can fall out of sync with some of the effects while they all shuffle around
There's no denying it, though the team do a great job with the limited resources they have, Duel is a large scale dark ride with hundreds of effects and a complex transit system. It needs a budget assigning to it accordingly to keep on top of it. I would absolutely love for this closed season Towers to go over and give Forbidden Valley and Duel the same treatment they've given Hex and X-Sector this year. It's that side of the park where I feel the problem attractions and less presentable areas lie since X-Sector and Oblivion have been cleaned up. If they could do the same to Duel and The Valley the park would be looking brilliant for 2014. Please Towers? Pretty pretty please? :*
