The first thing I clicked was the mushroom/waterslide/swimming pool thumbnail on the homepage, it isn’t linked to anything.
Thought I would let you know.
More padding-left in the main content area to set the text apart more from the left sidebar would polish the design a tad IMO.
There’s only about 10-pixels of whitespace now, that’s a little cramped 16-50px would be better.
50 pixels aligns the text with the edge of the color logo up top.
Be careful, the layout is so tight, adding the padding-left using FF to edit the Css was breaking the layout.
