Som people say its too boring in Qatar and in their context the only places to go is CityCentre,Villagio,Mall,etc.. Khor al Udeid dunes, Corniche,Frij Nasr and Al Sadd, but beyond that there is lot to see in Qatar, though its geographically small. provided that you got time and amenities in weekend start discovering Qatar on your own or by group which i would say is lovely and worth.
for intance you can log in http://www.qnhg.org/ (Qatar Natural History Group) who offers field trips to unknown places..

GoodLuck

I have Miles to go Before i Sleep and Miles to Go......
