Which category should I submit to?

Hi there.
My site is a worldwide travel website that has been around since 2002.
It has a Google PR=4 and an Alexa rating of 250,000 which puts it in the top 2% websites worldwide.
For my keyword, the sites name which is a single word, we have 8 entries on Google Page 1.
I've submitted my site twice to DMOZ in the past two years but nothing.
What am I doing wrong?
Many thanks
Cliff

You probably aren't doing anything wrong.

Some volunteer will process your listing suggestion in time but we can't predict who or when that might be. Elapsed times can range from a few days to a few years. There is no need to re-suggest your website and doing so could be counter-productive because a later suggestion overwrites any earlier one.

Be aware that top level Travel categories are generally pretty spammy and so aren't much fun to edit. It could be a while.
