Marrakesh definitely grew on me. Good to hear the night version is even better (stuck on episodic so can't play the bonus missions until the end of the year -_-). At first I didn't like it, but as I did more and more of the challenges, opportunities and as they released more escalations I kept finding fun new stuff to do.
The army base is great. The consulate is fun to sneak through, but a little limited and a lot of the unique kills require a lot of boring waiting around for scripted stuff to move. The biggest issue is that everytime you're going for the main mission you have to have this dead boring section of going between the two targets on opposite sides of the map. Especially if you're going for unique kills on each of them. Because of this I think the map is better for escalations that are all contained in one general area, because the areas are pretty fun and challenging. In a lot of ways it reminds me of a more secure, less fun, Sapienza.
Keep in mind we're still early on in Marrakesh missions. If Sapienza is what we can expect for the number of escalations in Marrakesh/Bangkok/Colorado, there's still a ton of content coming. Paris is probably the exception since they're front loading so much into it because it's the intro pack, but Sapienza should be a good judge of the amount of content each map should get.
