I visited here for an event a while back - and I realised I'd actually been here about 4 years before when I didn't really know the area, was scared of the Underground and frequently got lost wandering the streets of Glasgow. I'm proud to say I'm no longer scared of the Underground (well, most of the time) but I do still have an issue with navigating my way around Glasgow at times!
This is a large sized conference centre (despite appearances) and your experience might change depending on what you're there for. There's lots of rooms for breakout sessions, a good sized canteen/cafe area for meals and there seems to be a good mix of large/small rooms.
When I visited I believe the catering was done in house and I thought it was really delicious, which isn't something you'd normally say at a conference.
My only negative comment would be that there seemed to only be a few toilets in the building - perhaps I missed main ones somewhere, but there was only two cubicles so could be a bit of a wait during breaks.
There's plenty of parking in the streets surrounding, just make sure you have lots of change and aren't in a hurry as when I visited, a lot of the machines were out of order. read more
