When visiting Hurghada you have to remember you are in an Islamic country. Lately some tourists seem to forget this. You should dress properly. In Egypt showing your skins is not very polite. Men an women alike should use long trousers and long sleeves. Top less is forbidden.
Alcohol is available in hotels, pubs and clubs, but local religion does not allow locals to drink it (although some do drink beer). Locals do not like to see foreigners drink without limit.
