The UK is in the midst of transport strikes ( & postal strikes, & border security strikes) but we've been pretty lucky. Our (train) travel days had luckily been non -strike days so we weren't too affected. We'd planned to use Manchester as a base for day trips but due to the strike action we managed a day trip to York and spent the rest of the time exploring Manchester.
Our train trip from Manchester to London Euston fell victim to the flow on effects of 2 days of strikes coupled with a points/signal problem near Euston.
Normally trains run every 20 minutes and the journey takes 2 and a bit hours. Not this time. Several trains were cancelled and the train we eventually caught was late leaving because it didn't have a driver, then it didn't have a chef, then it had more toasted sangers but still no driver. Eventually they found a driver and off we went. We made it to Euston where there was still snow on the ground, then off to Paddington to check into our hotel - a smidge later than anticipated.
Again while in London the rail strikes had minimal impact - other than the difficulty of day trips.
Actually the main impact was our brother's plan to come to London to see us - due to buses replacing trains and train strikes he didn't get to London til mid afternoon (3pm) and we had theatre tix at 6pm.
Still it was great to have some time with him.
We didn't have a lot of time in London but we managed to fit in the musical theatre exhibition at the V&A museum.
We also found the theatre Cafe- which was so absolutely us. Everything was theatre themed even the signs in the restrooms.
Theatre wise we saw
Newsies (about the early 20th century newsboys strike in New York.
We also saw Back to the future the musical. It was good but the lead actors were playing Michael j Fox & Christopher Lloyd rather than Marty McFly & doc. (A minor thing but it niggled).
