First, welcome to the southern US and I hope your holiday is minimally impacted. Second, a few words about safety: winds will start to pick up and could cause debris, lawn furniture that wasn't already pulled in, tree limbs to become projectiles. Whole trees could fall. This means shelter in your room through the winds. Because Orlando is in a direct path (at least for now) you might have the eye pass overhead. If the eye passes overhead, there will be a period of 10-40 minutes (depends on width of the eye) where the winds will calm. You might be tempted to think the storm has passed, so be aware of the that lull if the eye does pass through your area. I advise caution about going out during the eye, even if you see others... there could be limbs about to fall at OKW. There could be roofing nails or other storm debris strewn about that you might not see easily. Wildlife might be out, but usually wildlife will slither/run from humans. Tornadoes can by tossed out by hurricanes, not always from the center, so even if there's not hurricane force winds near you, it's another reason not to be out strolling.
Third, I also encourage set up of towels like in the picture upthread for wind driven rain. Hopefully ants and other little critters don't come in, but I would be more concerned about the wind driven rain into the unsealed areas like a door.
You had asked about how to know what to do and when. I believe the second post of this thread, curated by GADisneyDad has several links for you to use. These news outlets will give you the advisement when to shelter in place. They will give you tracking updates where the storm is located. According to a Coronado CM I inquired on Monday, Disney will use the shelter in place (which means your room at OKW) as a curfew, because those rooms are outward facing. Although if your room is interior to a building (like Jambo house or Wilderness lodge) you may be able to stroll in the interior lobby area. If you are completely without food or water, then see what you can do to safely provision for at least overnight thru midday tomorrow. There are excellent posts upthread about room preparation, window safety and food/water set-up.
I hope you come through the storm safely and end up having a positive experience adventure to share with friends and family back home. Big hugs!
