We were at DisneyWorld when Mathew hit. At DW it was far enough inland that nothing major occurred weather wise. Moderate rain and wind but no worse than most any other summer storm. All four parks closed early at 5pm and were closed the next day. All roads were closed, no cars or buses allowed. Guests were confined to their resort hotels. On the first night sit down restaurants were all closed. Only the walk up counter take out restaurants at each resort were open. The lines to get food were around 1 to 2 hours.
On the 2nd night Disney opened up Disney Springs in the evening and provided transportation so guests could dine at the restaurants there. Of course those restaurants could not handle so many people with no other dining options. We skipped the Disney buses and used Uber to get there early ahead of the crowds.
All in all it was a minor inconvenience worth it to be safe. We were there 10 days and the 1 day with parks closed allowed the kids to sleep in late.
Irma is causing Disney to close parks early on Saturday and remain closed Sunday and Monday.
