I have now confirmed with the site and they have agreed to reserve an area for people who are camping.They have asked if i could supply numbers of campers by the end of April so they can allocate space in the camping area.
For the motorhome /campervans there is no booking and payment is on arrival and EHU is on a first come first served basis,so there plenty of pitches but we will be spread out.
There will be a more info in the February Journal
