Alternatives in case you're stuck
If you're able to walk, this may be the easiest option. Glasgow isn't a big city and the city centre to the SEC is around a 35-40 minute walk.
While Glasgow has night buses, they only run on Friday and Saturday nights and even the best route McGills' N38) does not run particularly often or close to the SEC.
The best option may be a taxi – either a black cab from one of the city centre cab ranks, or Uber or GlasGo private hire cabs.
