The United Kingdom is a beautiful place to spend a holiday and explore and it can be done without going on a coach holiday where you are forced to eat at six in the evening and are then subjected to an evening of "entertainment" whilst the driver and tour guide flirt relentlessly or even worse.
There is far more to Europe than the Costa's and other British holiday haunts.
There are even parts of the Dordogne and Provence the Brits haven't yet spoiled.
The USA and Canada are big countries which makes it very easy to avoid your fellow tourists.
Even the "hot spots" like Florida and Las Vegas need not be ruined by fellow British travellers.
