Carry On Harry Potter

I dont think this company exists anymore as we tried to book with them so we went with Brit Movie Tours and Im glad we did. They offer a bus tour of the film locations.
If you have kids they will love it.
Then again we’re adults and we loved it too. Anyway here is the link to the tour.

Like so many other companies, Carry on Tours promise a Harry Potter experience unlike any other. What sets this company aside from all other tour groups is that they offer their own self guided tour of the film locations used in Harry Potter free of charge.
Carry on Tour’s free Carry on Harry Potter tour is offered as a suggested try before you buy. The company do offer a £499 four-​day Harry Potter tour set all around England but suggest that before booking, customers take their own self guided tour of Harry Potter’s London to set the mood.
Because they offer a somewhat detailed plan for a self guided tour, the four day guided tour is not really necessary unless you are a determined fan. if you don’t like the sounds of their four-​day tour, I suggest that you simply print the free tour from their website and save yourself £499.
Should you choose to take the free tour, you will need to set aside a good day to fit everything in. Please note that this tour also involves a fair amount of public transport in order to get from one location to the other. You will need to make sure you allow time into your plans for this and that you have topped your oyster card up by at least £10.
I found the Carry on Tours website purely by accident, but what they promised is absolutely fantastic regardless if you choose to take the four-​day or the self guided tour.
