Whats wrong with the 3 minute walk to the bar at the top of the family enclosure ?
That's a rather generous estimate of the time taken to walk it. It's more like 5 minutes once you've been caught behind some old bloke going down the stairs, then squeezed past the kids queuing for food in the South West corner. Just enough time to get to near the front of the queue for a beer, before turning round and negotiating the same trip again. Plus someone of Fasto's advanced age will struggle with all the steps up to the top of the West and then back upto the South Upper.
