Holiday.pk Could be holiday park, pack or package. I feel that this is quite strong, all comments welcome. There may be a short while until full value can be appraised, when this TLD is more mature. .pk is Pakistan
sorry, not much, apart from pakistanis i am not aware of anyone else going to pakistan at the moment, so i would say high $xx
Since .pk could be associated with "park" in an English-speaker's mind, the value of the domain will hinge entirely on the acceptance of additional tld's by the typical English-speaking internet user. My best guess is that the max value for your domain is likely to occur 12-24 months from now. Over the next year, I suggest some minimal development on the site to get the search engines pointing your direction. Also, shop the domain around to some end-users. Current appraisal, low $xxx. Well-fitted, reasonably large end user, mid $Xxxx.
