Your homepage is an image with image maps which is also not the best for accessibility.
Also, Rooms and Facilities doesn't validate because you use and uppercase U to underline your h2s. You can remove them as you already have text-decoration: underline on your h2 in your css. Nursery Details also has some easily fixed code issues. The Contact page is a bit buggered too, but I guess its due to teh contact form, so no worries there.
