we're going to dw in aug and debating which to buy. i'm at a conferance for 4 days, then 6 days at disney and will buy a 5 day park hopper (i have 1 day left from our last trip). my wife and daughter (12) will have 10 days at disney. should they buy an annual pass ($364), with only a slim chance of returning in less than a year? is this their best value as opposed to a 7 day/4 option park hoppper ($332), or is the no expiration feature of the hoppers a can't be beat detail? thanks for your opinion!
