I think Cathcart is the stop before Mount Florida. Went to a pub near there after the Costa Rica game.
The queue at MF always looks a lot worse than it is. It moves pretty quickly but you do have to sit and listen to people from the east coast with their shite patter/accents for about 20 minutes or so, so can't blame anyone for looking for an alternative to that.
There's also crosshill, Queens park and kings park all close by, and for those that are able to then the walk to the town centre is fine as well.
