Do you guys think the preparation (youtube videos and such of the rides) took away from the surprise of seeing Disney for the first time? We are going with out 2.5 yr old this summer and i'd be upset for him if he didn't like certain rides.
hmmm....here are my thoughts:
disney world is incredible and surprising in its magic no matter how often you go and no matter how old you are!
there will be rides he won't like. some you might take him on and wish you hadn't, some you might wonder why the HECK he didn't like it, and assume tomorrow will be different, and most he won't like you'll know to stay away from!
as an ADULT, i think it might take away some of the awe-factor to know exactly what is coming up, but i agree with what another posted mentioned: kids do better knowing what is coming, generally. they do better with a bit of routine, and kids in toddlerhood feel such a HUGE sense of satisfaction and comfort at mastering a skill/event, which is why they can ride the carrousel 4 times in a row (or sing the Small World song for 30 mins. straight, or climb up and down the stair in the Italy pavilion in epcot over and over and over and over and over and over.......) and it still feels great, right?
i've found that even after going 4 times, watching ALL of the parks movies, singalongs, planning dvds, our home videos, etc., my kids still wanted to talk about what happens on each ride, what to expect, what happens before and after the ride, etc.
when you're there with your son and you have a chance to see it throught his eyes, it 'll amaze you how incredibly "surprising to the senses" (poor choice of words, but the only way i could think of to describe my thought) most rides are...at every attraction, there are characters (are they big, small? do they move? do they talk? are they real? pretend? do they move at you?) there is sound (is it music? is it familiar? is it loud? will it get louder? is it a scary sound?), there are lights (are they bright? dark? are they flashing? will they go out suddenly?) there is the seating (sitting by self or on a bench? seats soft or hard? do the seats move- fast? slow? bumpy? stop suddenly?), etc. etc. this doesn't even include the surprising amount of stuff that gets sprayed/shot at your face level during rides...smoke ring during woozles scene in pooh, scent in journey into imagination (or maybe it was just a loud sound that startled my kids here?), water in philharmagic and magic carpets and voyage of the little mermaid in MGM , etc.
when i think about HOW MUCH processing all of this requires from the same little kids of mine who, for example, freak out at lunchtime when their sandwiches are cut the wrong way while sitting at the SAME table with the SAME people at the SAME time as always, i am AMAZED that we don't have more resistance to rides than we do!
we have an incredible time (which is why we keep spending the $to go back!), but we prepare our kids for what to expect each time.
not sure if this perspective will be helpful to you...
have a great trip!!!!
