Yeah at Disneyland the outside queue is very short. No creepy looking garden like in Florida. Also at Disneyland there is no "5th Dimension" room that you travel thru before the drops. And from what I've seen from photos online, the boiler room queue is definitely larger and more themed in California than in Florida.
you might try the search feature--this has been discussed multiple times, and there is a thread that is no more than a page back in wdw general discussion where we have outlined the changes, so I see no point in typing them all again.
