arriving too early?

[pu55ycat1]

Hi everyone - i've just discovered these forums and found them a wealth of useful info, so hoping you can help me with a question... what happens if we get to the gates before the offical opening time - do they turn you away or let you queue outside? we're going in a camper this year and so hoping to take advantage of the earlier opening time and get there asap. therefore planning on leaving s wales extra early to be cautious, allow for traffic and mishaps etc and get there no later than opening time. however, bit worried if we end up too early we might get turned away, then stuck in a one way system so that when we finally find our way around and back to the gates there'll be a massive queue and we'll be at the back of it?! any thoughts anyone?

thanks!
