We joined the mob of stroller-wielding families this past Saturday, visiting the OSC. It was fun enough, except for the small matter of getting around the six-story building.
Hi -

Several times over the last few months that my young family visited
the OSC, the poor state of access was saddening.  Half the elevators
and some of the escalators were not working.  For a deeply multilevel
structure like yours, this is unacceptable.

Worse, there was no staff nearby to operate backup machines like the
big cargo elevator.  Whole lines of families were lined up for tens of
minutes, waiting for elevators that never came, or only went the wrong
way.  Many took the risk of taking the strollers onto those long
escalators or steps.  I witnessed several near-accidents.

This is not an isolated issue, and it's not just a matter of "sorry,
the elevators are under maintenance".  If you know that access is
impaired, put enough signs and staff on duty that people can get
around safely and timely.  If you can't, then put up a big warning
sign at the OSC entrance.  To do neither is to frustrate and endanger
your visitors.

Thank you for your attention to this problem.
