Extened magic hours

[momof4kid]

Hi, I'm not sure if this is the right spot for this, I'm new to DIS,but am loving it. I was wondering if anyone has used the extended hours before and after the regular hours during the busy time of spring break. I know it's very crowded anyway,but I'm not sure if it would be better or worse.
Also, does anyone know where I can find the list of the rides that are open during those extended hours.
Thanks for the advice
