Hi,
The Jazz rooms are also preferred, and a little further down from Calypso - so if you want to be really close to the lobby/food court & buses I would say to request Calypso so they can do their best to allocate you that building.
I stayed as ASMu back in 2015 and in the Calypso building on the ground floor facing the car park - it was a perfect room and only a couple of minutes to everything.
