hi, when u say libya do u mean tripoli, or benghazi and other cities as well.
ill focus on tripoli, although i can give info on other areas if needed
if your looking for international hotels in tripoli, ur stuck with the corinthia and the radisson for now, although four points by sheraton will open in september
there are quite a few local hotels which provide what the internationals do at far more reasonable rates.
there are several travel agencies, the 1 i can vouch for is Matia tours, there are several others, but im not sure if they are active at the moment so soon after the war. if u go to
http://www.yellowpages.ly u can search for travel agents etc
for visa assistance, generally the our companies can help you out with that, its quite a big business here in libya, but unfortunately they are mainly in libya, working for companies needing to bring people in, not generally accessible from outside.
attractions, i guess near tripoli there are a few roman and greek sites, leptis magna would be 1, i cant remember the other. a bit further out into the nafusa mountains you have the old amazigh(berber) cities, with there history. after this war, im sure the famous battlegrounds such as misrata may be included in future tours etc.
do's and donts? theres a saying here in Libya, "Libya Hurra" meaning Libya Free. there really isnt many donts anymore, feel free to publicly talk about anyone in the government etc.
on a serious note, it wouldnt be wise to praise gadafi or mock/question/belittle the revolution, you will be very hard pressed to find a single libyan who didnt lose a relative in the war. alcohol is still illegal, although available.
generally speaking its like most other conservative middle east countries in terms of dress and actions.
any additional info?? make friends with someone with weapons and go shoot some rockets, throw hand grenades, fire off some anti aircraft weapons.
lots of fun
hope this helps
