Right then, I'm a bit confused about the way fastpass works. This web sites explanation mentions about a "1 hour window to return to the ride". Does this mean you have one hour after your return time to go on the ride?. Also I saw in the Brits Guide a mention of getting another fastpass before you even return for the first one. How does this work as I did not really understand it? Sounds like there is some secret about the use of fastpasses but I need it explained better. Thanks
