We keep an eye on the Foreign Office web site which gives advise to travellers

Check out:       www.fco.gov.uk

This web site gives an update on the current political situation and advise on health issues.  It is worth looking at.

Currently Cairo appears safe - I have never had any problems with groups.  One time, some girls were in the Khan el Khalili when a bomb went off in the locality - they didn't notice anything unusual!  I was quickly notified by my network of friends so I could track them down and check everyone was safe.  

Turkey is more on the cusp of current politics.  I go to Istanbul regularly and have not had any problems.  The people continue to be friendly and try to make your holiday as special as possible.  If there were specific threats or problems, I would have to re-asses the situation but as things stand at the moment, I feel quite safe taking groups.

I have British and local friends in both Cairo and Istanbul.  I do check with them constantly as to what the situation is like.  I would not knowingly take groups into dangerous situations.
