most appropriate category?

Hi, I've never had troubles finding an appropriate category, but perhaps someone can give their thoughts where:
http://www.thebigdomain.com
...should be submitted to?

These both sound reasonable, but the other sites in these categories are not really in the same business
http://dmoz.org/Recreation/Travel/Lodging/Directories/
http://dmoz.org/Recreation/Travel/Guides_and_Directories/

I think perhaps "speciality travel"
http://dmoz.org/Recreation/Travel/Specialty_Travel/
...would be more appropriate, but there is not a 'luxury' or 'group' travel section...

Any thoughts appreciated... Thanks

I would choose Recreation: Travel: Lodging: Directories, which seems to be the most specific category.

Yours,
Robert
