I don't know what it would be like for New Year, but we were
there in May and enjoyed our stay. The showers etc. were clean and well-maintained, the staff were friendly and our pitch was pleasantly situated in a slightly wooded area. There is a fair amount of road-noise, but it didn't keep us awake. There is a health club/indoor pool attached, but charged extra - we didn't use these, but they certainly might be useful for a winter visit.
