EMERGENCY SEAT AT DISNEY CHECKIN?

Folks - We pay 50 e/w at checkin for emergency seats - however, wondered if we were able to request this when we checkin at Downtown Disney for our inbound flight - or do we have to request this at MCO - which of course means getting there 4hours before.
Thanks
Sandy

I have a feeling it has to be done at the Airport. I maybe wrong so if I am someone please correct me.

There is quite a long thread here, about DTD Check-in.

On page 2 it says you can get exit row seats there, but I have never used it, so can't comment.

Edit: Aren't exit rows on flights over 8 hours more expensive than £50 now, as well? [?]

Further edit - V-flyer FAQ's. Flights over ten hours are now £75, so not the MCO flights.
