Socotra is an incredible place ... it a Unesco place as well.
But You have to catch an airplane from Sana'a' ... there should be quite frequently flights in a week; I don't remember that because I've been there many years ago. the place is beautiful. I suggest yo go there, even if Yemen is by itself a fantastic country and if You decide to do not fly to Socotra, You will see an unbelievable country by the way.
Good Luck everybody!
