Don't be afraid to toss whisky (although there weren't really places to get rid of whisky in the CPT one which was a bit weird...), some of the pours can be overly generous. Pace yourself, drink water, eat and be sure to get an idea of which stand you'd like to try their half-time bell special and get there (for me it was three ships at the CPT one! I also managed to try Bruichladdie's Black Art and the highland park one which was a Bottega Whisky Club single cask bottling).
I would not try every expression or even every stand, you won't make it out alive. Try things you won't be able to buy in a bar or afford. I wish I'd been sensible and tried more Campbeltown whisky, I didn't even though I fell in love with The Gauldrons...
I was quite impressed with Bunnahabhain 12, Auchentoshan Three Wood and Redbreast 12. Certainly expanded my palate!
It is generally recommended to start with the less peaty offerings however an option, if there's something you're really keen to try, try it and then go clear your palate with some food and water.
Chat to the people about the whiskies you may learn some interesting things!
Anyway enjoy you'll have a blast no matter what!
