I flew to Newquay a couple of weeks ago.
Landing fee was £19 for a PA28, although this may have been cheaper than normal as it was their 'GA Weekend'. Handling is no longer mandatory below 3 tonnes MTOW as per their AIP entry. Nonetheless, the handling agents who took our landing fee were very helpful, offered us a (free) cream tea, and were more than happy for us to use their briefing facilities.
We hired a car from Hertz onsite which cost £40 for the day (prebooked) and allowed us to get around Newquay, Padstow and the area without needing multiple taxis.
All in all we were made to feel very welcome.
