In answer to your question..........

Castellon airport is CR#P.   IMHO.

I booked in advance (2 return flights)as thought it would
be a better bet than Girona, how wrong I was.
Facilities almost none, only one coffee machine that was
inoperative and a soft drinks machine available.

I'm not impressed with Ryanairs' Maintenance Facility
either, reports, flight back to the UK had a 6 hour delay
because no engineer was available to fix the aircraft, and
that passengers had no food or drinks available to them until airport staff went to a local store (not sure how far that was) to purchase sandwiches and drinks.

I'd also check on car parking charges, I was told it would be
expensive, there were no charges when I used the facility as
the airport didn't have any barriers or means to charge people
for parking.

I don't think it's a patch on Reus, El Prat or Girona.

So to sum up, it's a shambles.
