What do you find is the most entertaining queue line at Alton Towers? Would it be Rita's Cattle Penning, The Oblivion Electrode/Lord of Darkness TVs, Spinball's Games, Duel's graveyard/haunted house?
Personally I'm not too sure which I like best, I thin Oblivion has the best Queue line TVs, but Duel has a brilliant themed queue, as well as Battle Galleons interactivity queue. For obvious reasons Rita/corkscrew are one of the worst and I find Air pretty bad too with like 'bus shelters' if they open up the longer queue.
I think it really does help the time fly if the queue is well themed, shows different angles of the ride (or in the case of Hex build it up) and give something the guests can interact with.
