Baby are no longer in Tiny Town at EMA. They have moved to within the Donington Hall site.
You won't get an easy ride just walking into the place and asking to see someone. Not that long ago a couple of nutcase disgruntled pax turned up and caused havoc, so unless you have a reason to go there, then pitching up won't generally be appreciated.
The receptionists aren't likely to start giving out information to just anyone who turns up, even if they do know.
