Not having sympathy is not the same as gloating. Not sure why one poster has said this about the OP.
I have no sympathy because it’s been said this whole bridge thing would be kept under review because the virus has not gone away. We’re also told the travel bridge would be under review (subject to change) if the virus has an outbreak, to expect localised lock downs because the virus has not gone away And there can be localised outbreaks . So if we know the virus has not gone away, that localised lock downs may need to happen if there are outbreaks, why would anyone be surprised that when there’s outbreaks in Spain, the travel bridge is changed to include quarantine. It’s not a surprise. If it gets worse, travel to Spain may stop altogether.
So the people booking trips did so knowing the virus is still around, that there could be outbreaks, could be lock down and could have impact on the travel bridge. Why do they need sympathy for the obvious? Feel sorry, yes but sympathy no. No one wishes for something bad to happen to people. It’s a different story if they know there’s a risk but decide to roll the dice, take their chance and do it anyway.
Anyone booking any new trips until this pandemic is over is taking a risk and they’ll need to ensure they can afford that risk - be it quarantine, getting stuck in a foreign (or local) lock down, trip cancelled etc.
It’s not as though they didn’t have warning because we all have.
