In reply to StuDoig:
Having now been three times over our week long holiday, my gripes would be:
The colour of routes. Often identical colour next to each other or two very similar on same panel, e.g. yellow then yellow + brown etc. More care needed! Too much wondering is that orange or red?
The bouldering area: would be better if one colour used to designate routes within a certain grade window as is common elsewhere.
