A few tips from my recent visits:
Re parking if you want to avoid the toll or avoid clogging the limited existing parking around the Cave there is extensive free parking up by the ski slope which is accessed by driving up the steep narrow road past Parisellas Cafe. It’s then a 3 min downhill walk direct to the Cave through a gate in the fence of the Happy Valley garden. Stout walk back though.
Following loss of van found cheap downmarket accommodation at the White House hotel on the sea front at £34.50 for 2 of us last night through booking.com. Bargain. If you don’t expect much you won’t be disappointed.
Overnighting in a van on the Marine Drive seems fine with the friendly wardens. Best spot is up a concrete road on the left just past the Rest and be Thankful cafe. Great views but no signal where you park but if you walk 50 yards up the hill to a fingerpost there is a decent signal. An alternative is the lay-by opposite the St Tudno graveyard which has a toilet just opposite.
