Nice report on a lovely park.
I should point out, however, that (besides Samurai being knackered) the superior ride operations and longer circuits at Lightwater Valley are entirely down to having less guests and shorter queues compared with the likes of Thorpe. Samurai gets 45-60 minute wait times as it is, so really can't afford to run for any longer, which is a shame.
Certainly a benefit to visiting smaller parks though. And, indeed, The Ultimate and Raptor Attack in particular are outstanding rides.
