Thirded. Syria (and Lebanon and Jordan) are nothing like Morocco and Egypt. From my experience of Turkey, I'd say you'd have far more problems with 'faux guides' in Turkey than in Syria!
I'd say around 99% of the time in Syria, if someone comes up to you and strikes up a conversation with you, it'll either be totally innocent and done out of curiosity/friendliness, or a very low-pressure attempt to sell something or to tell you about a shop that they own. Syrians are the best thing about Syria, so do make an attempt to engage with them whenever you can.
I know that most Moroccans are lovely, and that the guides and beggars there are only doing what they do because of poverty, and that I'm very rich compared to them, but I also found Morocco very hard work - after a week there, I just ignored pretty much everyone, which I really don't like doing, and which made me feel like a bit of a bastard.
Syria's not like that. I've ended up in strangers' homes many times, and sharing cups of tea and cigarettes with strangers more times than I care to count. Even in the touristy-souk bits of Damascus and Aleppo, the traders are pretty good natured, and will usually just ask you how you are, how long you're spending in Syria, where you're from, tell you a little about themselves, and then tell you that they have a shop. If you're obviously not interested, it's usually not a problem - it's not like Morocco, where you're often forced into shops more or less against your will, or sometimes quite deviously.
Beggars in Syria are few and far between - if you spend a whole day walking around Damascus or Aleppo, you'll probably only see one or two. And the locals will always give very generously to them. I think I give far more to beggars, and tip far more, and spend far more in shops in places like Syria and Jordan, due to the comparative lack of hassle.
Touts can sometimes be a bit of a problem in Palmyra, Apamea and Bosra, but they generally aren't too persistent, and will usually only bother you for a couple of minutes if you're good-natured but firm.
In four trips to Syria, I've never once encountered a 'faux guide'. You will get real guides of varying degrees of competence offering you their services at tourist sites, but if you say no, it's not like Morocco where they'll follow you around for the next hour and then demand payment in order to go away. A lot of guides are actually excellent value, know their history, have superb English, and are well worth engaging.
I'm not saying that Syria is totally 100% hassle-free, or that the country is completely free from persistent touts. But the level of hassle is so low, and the overwhelming majority of Syrians are so lovely, that it's somewhere where you really should just relax and make an attempt to engage with the locals as much as you can.
