We will be visiting London in December just before Christmas to go to an event at Excel. We usually stay in Farringdon and travel on the Elizabeth line which is straightforward but looking at alternatives to try and avoid crowds as much as possible. We are coming from the North of England and wondered about driving to north London to a hotel with parking or possibly staying nearer to the Excel. Budget wise probably looking at a Premier Inn or in that range. We need to be able to get back to the hotel late Saturday pm. One adult, one older teen. Any ideas?
