Hi Jonah, 
Regarding the excursion, here are the timings: 
You will spend 1 hour visiting the mosque, Corniche and Etihad square are then for photo stops and you will be at the Mall for 1 hour. 
There are 25 travellers on this trip, 6 men and 19 women. Their ages range from early 30s to early 80s. 
There is just one person flying from Birmingham at the moment. 
Many thanks,
Vickie
