If you're a Scotch lover, there's an experience worth seeking out beyond going to distilleries. I've never done this and I admit the advice is old so it might not be available and/or the price may have doubled or more since then. If it exists though, it's worth seeking out as an experience if you're a Scotch lover.
I was told to find a place that has all you can drink Scotch (or similar) and carefully sip your way up to the stuff that's discontinued and rare. It's not cheap, but ultimately far cheaper than the costs of even getting a whiff of this stuff outside of Scotland.
The person I spoke with in Hong Kong said that for around 100-150 Euros, they were able to enter the realm of getting access to unlimited drams which came with occasional tastes of stuff in the 20-30+ year range, some discontinued, some from distilleries that no longer existed. Basically she said it's unlimited Scotch on a fixed list. But at the bartender discretion, they gives access to taste the rare stuff. She said if you did the unlimited Scotch with a friend, the bartender hinted he was more likely to unlock higher end stuff than if someone did it on their own, but she doesn't know if he was being truthful or hitting on her and her girlfriend.
She said it wasn't a Scotch library, just a place locals frequented. She said she compared the price paid vs the Scotch consumed and concluded it made no sense for a local/regular, but could make a ton of sense vs individual pours of higher end/rare Scotch. She is not a Scotch lover like her girlfriend but really enjoyed the 20-30+ year old stuff they got access to.
I spoke with another friend who enjoys Scotch and they said they ran into something similar 3-4 years ish years ago (but not the same). A fixed price for unlimited Scotch offerings from all the nearby distilleries. However, in his situation, he did say that there wasn't access to anything rare. It was just the normal offerings that the distilleries had on their tours. He also said the value wasn't great (even if it was basically unlimited) and within a few drams, his tastebuds were shot so it wasn't really even a helpful experience in trying a variety of stuff. He did admit he went there after a tour though, which he thinks might have contributed to it being poor value/taste buds overloading. I completely forget which area he was though.
EDIT: Something like this, but not specifically this?
