No idea on the disability pass... Food wise we usually do at least one Character meal... I like to do it the night we arrive sort of a kick off to the trip! The kids love it... its pretty normal restaurant food. There aren't meal plans at disney the way there are at universal studios (Although I didn't really like how it worked out at universal... I like eating when we're hungry, not given specific time slots).
They do rent strollers... My kids are not big into the stroller, however its nice for carry all the stuff... They do rent them there, not doubles though.
Universal... just an fyi in October it will be pretty gruesome... Might work for some families, but I've been as an adult and wouldn't take my kids during halloween themed stuff at universal... lots more gory blood/guts type horror where Disney in Oct is more cartoony-halloween...
We are waiting to see if we can get there in OCT this year as well!
