I'd take all of your internal links and re-write them to include unique content. I have randomly looked at several pages, pulled out a single line, and googled it "with quotes". Each instance showed at least 4 other sites with that exact phrase. your main site is listed: http://search.dmoz.org/cgi-bin/search?search=sunnymaldives.com which has much of the same content as you it seems, so that may not help either.
althought i have some affliation of the that site. www.bookmaldives.com serves a different purpose and different segment. and it is again a different site. so i think it has to be listed too. right
That would depend on whether or not it had unique content. A bunch of sites that server different functions but all have the same content have no reason to even exist, let alone exist in DMOZ.
