I have used some of these sites for years and others are fairly recent finds but I find all of them useful when planning our travels!
The BEST site for planning any train travels anywhere in the world
Europe’s biggest online booking tool
In my travel kit I have the following!
Kindle Voyage E-reader
I can’t do without books to read but having them all on my Kindle saves space and weight!
My Anti-Theft Cross-Body Bag
I have this in red and boy did it come in handy when we were in Paris last year. It is an invaluable part of my travel kit.
I use Viator for most of my tours!
