We loved Innoventions, primarily because of the CM's!
DS was 2 on our trip last April & we celebrated his birthday.
The first CM we saw at Inno saw his birthday button right away
and asked us if he'd gotten his "Birthday Phone Call?"
We said, no, we didn't even know about it!
She asked us to step over to where the Segway demos are,
she stepped into a closet & dialed up Goofy & he called back a minute later asking for our DS and wished him a Happy Birthday!
Then, we sent video email over & over again to several family
members, the CM there was very sweet & said we could send
as many as we wanted to shoot.
We just waited for whomever walked up after us,
then we stepped right back in & made another, and another, and another!
Then, we had a nice conversation with an exchange CM from
Hong Kong
Disneyland - he loved showing us & helping us do this electronic
gismo where you have to do team-work to cover up things
to make lights go on & off - our DS loved it!
hint: we especially enjoyed talking to all the exchange CM's
we could find (there were many, they were training before their opening)
and we got each one to sign DS's autograph book
- writing our son's name & their's in Chinese!
The CM's really seemed to enjoy it, too.
Then, DS started having a bit of a meltdown because of so much
interaction, and another CM went behind to the robots and
built DS one and presented it to him, which calmed him down.
We still have his "bot" as he likes to call it.
As you can see, we had fun there, but I can certainly see where
it would be age-defined to how much time/fun one would have.
