Hi we have flights booked to London on Easter weekend (from Dublin) and were to stay with relatives but circumstances have changed and we now have to pay for accommodation. I have been looking into options as it is so pricey and was pondering staying outside London for 2 nights and then in London for 2 nights. My DS loves trains and saw Watercress Valley Park looks relatively near London. We would also like to see Windsor but I don't really know where would best to base ourselves? I think the railway would be great so would favour that over Windsor if needed. I would appreciate your thoughts!
