Thanks Mer9 for answering, you have helped me a lot!!I think we will go on friday, because that day it will be easier to rent a car for 24 hours to go from gatwick to the park, to stay the night with my sister in Belvedere and next day drop it off in London.We might not get to the park until quite late depending on the flights we get (thursday night or friday morning) if we get there late we might get a fast track ticket, do you know if there is one that includes the mazes as well? and can we book it online?
