I am so sorry to bring this topic up again. I know it has been hashed and rehashed. I am very familiar with the limitations of ice availability in Europe. But an ice-dependent friend is going to join me for the Scotland-York-London part of my 2019 trip, and I want to provide accurate information about what she will encounter.
As far as I can tell, twice a day (around breakfast time and around lunchtime) it is her invariable practice to get a large cup of ice and pour in a bottle of Diet Coke (preferably already cold, I think). This is not a problem when traveling in the US because essentially all hotels/motels/fast-food outlets have limitless ice. I imagine she settles for a fountain drink, rather than bottled, if she has to when away from home/hotel.
I know there will not be ice machines in our budget lodgings. Do fast-food restaurants in Scotland and England sometimes/always have ice dispensers so my friend can buy a cup of ice or, in a pinch, get a large soda in a cup full of ice?
If this is going to prove impossible, I want to warn her.
