Wot, sorry about that, I misunderstood.
Seychelles is a small country (island), but a big holiday resort and relatively expensive. It is 'nearby' where I live (Kenya) and I know lots of people who have been there, even for their honeymoon. Therefore I rate your travel.com.sc and seychelles.com.sc at least as high as casino and poker. Your idea of developing them is a good one, these names beg for developing
Like mentioned in other posts also IMO the com.sc listing at Sedo is fraudulent or misplaced and you are the right owner of all your 4 .com.sc names. Furthermore, don't worry about the "transfer prohibited" at the whois, at my registrar they first told me that I could not transfer it to my name, but after Sedo stepped in it was done in a few days.
