At Crac de Chevaliers, there is a restaurant with a camping area and basic rooms, just downhill from the castle. Called "Round Table Restaurant & Camp", I think. The folks at Al Qalaa restaurant (excellent food, btw) recommended it and gave me directions.
In Damascus I stayed at Sultan hotel, parking (my motorcycle) in a nearby parking garage at about US$8 per day. The hotel is about a 10 minute walk from the souk, old city, etc. The hotel is in the LP middle east guidebook, also findable via google. If you pass the hotel, with the hotel on your right, go one block and turn right. Take the first left, the street will bend to the left and go uphill, the parking garage will be on your left. Just a short hike to the hotel.
