hi,travelling by road to property in spain on christmas day will there
be any motorway services open to re-fuel

When I was in Spain 20 years ago, the Jerez-Sevilla Autopista CAMPSA
stations were open. The main gasoline station, also a CAMPSA, right
downtown in the medium-sized town I lived in was open as well, but
none of the others were.

But that was then...

Hello marpet!

I'm french and every year I travel to Portugal by car. I can tell you
that all the french and spanish motorway services, that are located ON
THE HIGHWAYS, are always open 24/24h, 7/7d, including non-working days
(also, that's why travelling on highways is so expensive in
Europe...).

I hope I answered to your question, and I wish you a nice holidays in here ;)

Sincerely,
frantugais.

Hi,

all the stations of the open freeways are open by day 8h to 23 h. all
the stations of the HIGHWAYS are not 24/24h, some close 6 hours at
night (24h to 6 h).  Yes, it is certain that the stations open 7/7d
365/365d.  In Portugal better.  In highway they indicate the distance
to next and whichever it would lack you for the following one. 
Anyway, there is no problem to travel, to refuel, etc those days. 
Except the price of the gasoline (sic).
