There are a couple of decent hotels on the Braehead complex. I tend to stay at the Travelodge which is cheap and clean, but a better bet might be the Premier Inn which is just round the corner. As you'd expect at a shopping centre food and drink are plentiful and despite the slightly surreal experience of watching a game in a mall, it is generally a decent atmosphere and a good game.
I fly up from either Stansted or Luton to Glasgow which is generally about £19 each way, add a few pounds for a bus and it is not a bad trip to make.
