Yes, I did see the earlier post. That is why I suggest an email might be the best option. I know their website appeared to be closed, but I've just been looking at it now and they give dates for 2007.
Like you say I can only assume there is a possible error as the information shown on the Mundomar Website clearly conflicts with what the other Member has stated.
The calender shows December 25th highlighted as being a day the Park is open, but on the same page they state it is closed on Christmas Day.
I mean wheatcrunchie says they have received an email confiormation saying that the Park opens from February 10th which dies not agree with the calender on the website which clearly shows 26th february 2007.
