i totally agree with some of the previous post-ers - Independant travel is really easy, allows you to go at your own pace, make itenary up as you go along etc, etc....and because it's Syria when you actually do arrive at most of the historical sites you'll have pretty much ALL TO YOURSELF.
I accept that i travelled with a friend, which made things even easier for me, but logistically getting around Syria was easy peasy. We arrived in Damascus, had only 10 days, and just planned our course of action from there.!!
The way we got to see A LOT was, as some previous people have mentioned, was to hire a car and driver. Depending on what you want the cost will vary (ie.longer days / more sites = more money), but i can't remember us paying more than $US75 each ($150 on your own) and that was for a really long day from Aleppo to Palmryia, via Rasafa (which was Amazing IMHO).
As others have said you can easily use the public transport which we did at a couple of points, but depending on how much you want to see (and in Syria there is LOADS) you can only generally fit in one, maybe two sites per day, as opposed 3 or 4 with car and driver. So if you want to see them all you'll have to factor in extra hotel nights. Hama for 2 nights was a really good base for us - and we stayed at the Hotel Riad (or it could have been the other one in LP - HOtel Cairo?) which offered the car and driver
We did not get any history overrload on any one day as the beauty of Syria, amongst many many things, is the historical stuff they have is so VARIED - so it's quite hard to get bored looking 'at the same sort of stuff'.
So i guess it's down to your budget seeing as you've got no problem doing it alone. I've gone on for quite a bit as i really really LOVED my trip and will be going back I'm sure.
GO GO GO and ENJOY ENJOY ENJOY
