That was not something I needed to read at the moment can only hope there's not another next week!

Probably not -they are previewed I think for weeks -like the other strikes mentioned.

As tourists just avoid rush hours and walk. That's what I did and I was just fine and I live and work in London. Tourists can plan to not travel early morning and evening rush hour - go to a pub!

Avoid rush hours, use the buses so you see more of the city, walk. Replan your days somewhat.
You aren't tied to office hours like the poor souls struggling to get into work, not only dealing with the tube strike but the ongoing strike on Southern Rail (which also affects on occasion the Gatwick express).

There are no strikes that I know of planned for tubes next week. They are announced well in advance generally.

My daughter left her house near Baron's Court tube stop at 0715, rode a series of Boris Bikes (changed every 30 min to keep the cost down)(may I still call them that?) got to 1 More London Place by 0900 after a quick shower at the gym. She said it was fun and exhilarating.

By 1900 the Tube was running again, which was good because she does not have proper reflective gear.

It was hard to find a docking station near work, she said, because that app wasn't working.
