in November. Right now the weather is too hot to enjoy much of anything. Many of the safari companies offer an overnight package. It is very expensive, but an experience not to be missed. Sealine is not worth much of anything, in my opinion, and I have never been to the resort in Al Khor. check the threads on what to do in Qatar. You could spend a day checking out all the forts in the North. They are pretty cool. Also the abandoned movie set/fishing village.
