England: Can we ask about travel impact of BREXIT and Thomas Cook?

Violence? What is your historical basis about expecting violence in England during your visit?

I was in London at the end of March last year when there was a huge protest about Brexit (hundreds of thousands of people) as it was assumed the UK would leave the EU by March 29. People came to Westminster from all over the UK on that last Saturday before March 29. You must have followed the news given your current concerns about safety. There was no violence.

I am returning to England in under a month and will be in London around the time you will be there and I’m absolutely looking forward to it.

Thomas Cook went under for many reasons including more & more people not relying on travel agency type packages, travelers preferring to plan their own trips, discounted airfare from low cost carriers and the growing popularity of Airbnb. So the failure of Thomas Cook is not the result of merely one particular reason including Brexit. How does the bankruptcy of that company affect your trip?

Logical discussion means removing perceived hyperbole about violence. Now have a wonderful time! That is an order! 😊🇬🇧

Yay, Continental! I agree, have fun! You will be on vacation! I have stopped watching the news about some of these topics like Brexit as the reality rarely turns out as disruptive to travelers as the news analysts and reporters speculate.

Thomas Cook, while a large company compared to many, is only a small part of the travel industry. Many people will be angry if they lost their holiday money, but not to the point of riots in the streets. You would only be impacted if you booked any of your travel through them. And you can't discuss Brexit without politics because it is politics; and no one knows even now what impact it will have. Probably will be delayed again is what I have my money on.

Thank you everyone for your insightful replies! Most informative and reassuring!

I don't know what is happening, but I understand your concern of trying to undergo a vacation when your location is bound to be in turmoil (somewhere on a sliding scale at any rate).
I had plans for 3+ weeks in Spain that included Barcelona at the end. Shortly before, there was the 'change of government' to Catalan 'power'. There were protests, travel disruptions and uncertainty. I pondered over what I wanted to do or what I could tolerate in the uncertainty factor. I looked at options and realized I did not want to spent the better part of 3 weeks in other parts of Spain worrying and having to keep informed about what was going on in Barcelona. I decided to remove Barcelona from my itinerary....except that I had to fly from that airport. So I went to Valencia where there was a bus that dropped off at the Barcelona airport. I booked a hotel near the airport, so that if I had to walk there due to taxi strikes or traffic issues, I could. These actions meant I had as much control over my plans and enjoyment as I could arrange. Of course, things were never as tumultuous as the first week or two, but I could watch the news (not that I saw more than one night of it) and not have to wonder if I was going to have problems or make changes on the fly.
Some people need alternatives in their pocket. It may be a lot of work, and others poo poo it as 'asking for trouble', but it is the kind of effort that means if there IS trouble, they know exactly what they can do and hit the ground running.
Only you know your comfort zone under circumstances of change on the fly; or if you can afford to be delayed on your return - either in time or $$. Don't let anyone convince you you don't need to consider options, if options are what you need to embark on any of the trip. Do what works for you - despite the fact that no one knows what exactly will happen.
Also consider, that as far as demonstrations go, the police tend to have some kind of way of informing the public about these. Barcelona's police actually posted on their Twitter feed (in english for tourists when important). You can still get about - at least on foot- by just moving several blocks away from the location. This was the advice given when Barcelona was undergoing massive protests and demonstrations. If a hotel, they could often find alternative exits for their partrons and would help to keep them informed. At times, it was recommended to plan by bringing food into the rooms if the protests were outside the hotels (as happened for those on las Ramblas). So, you aren't totally alone. The city will have plans and there will be ways to keep yourself informed. Be glad the main language is English.
Have a great time.
