The number of sights and calibre of attractions pales in comparison to Dubai, but it is far less crowded here and people are exceptionally friendly. I think at this point, one day is enough to see Doha. For architecture fans, the new business district over at West Bay may be worth another half day of exploration.
Thanks for the update, so, if they throw a free night at me and I have the time, I think that I would actually take them up on their offer. Great photos, thanks.
