Only the top level items need the class="parent" attribute.
The problem is with the asp code:
in the links. if you are going to hand edit it, you need to remove that from the links. for example:
<li><a href="<%=assumedRoot%>hotel-south-west-scotland.asp">GARDEN SUITE</a></li>
<li><a href="/hotel-south-west-scotland.asp">GARDEN SUITE</a></li>
