I'd pay double anywhere else if it means I don't ever have to do it again at a nameless East-Anglian coastal establishment not a million miles from Yarmouth......
The coldest water, biggest wave machine, highest jumps, hairiest-arsed ex naval 'gun carriage' type instructors and a serious sense of humour failure all round....admitedly mine mainly!
When the liferaft failed to inflate and we had to pump the feck** by hand only to be be told at the end of the course that they NEVER arm the thing, thereby saving themselves the re-arming charge I nearly commited a criminal offence but decided said gun carriage carrier type was a serious lump.
