That sounds about right, I went on one of those Christian event days where there was 25,000 guests and the most we queued was 90 minutes for Oblivion.Whilst the queues at Alton can be just as long if not longer then Thorpes, the parks rides have higher capacities meaning that whilst you may queue the same amount of time, it doesn't feel as long as you are nearly constantly moving.I'd rather queue 90 minutes for Oblivion for instance then 20 minutes for Vortex.
