It really is. Just takes pretty massive coordination if it's going to be over enough road to help.
I went to Disney... Now Irma is supposed to roll up the whole Peninsula. Hopefully it should be <CAT4 by the time it gets here.
Last I've seen it's expected to make landfall at cat 5, probably maintain at least cat 4 as it travels up the state -- though it should be noted that irma is
fucking huge. Disney's close enough to florida's tip it's going to be hammered shortly after it hits. Also moving plenty fast. It's damned unlikely there's going to be enough time for it to get to cat 3 or below before it passes the top of the state, never mind the area around disney.
If you're saying you're visiting on vacation, I'd heavily suggest you cut that vacation short and get the hell out, like... well, today would be best. Tomorrow would be okay-ish around that area. Saturday or Sunday it might be past the point evac is all that possible. Hopefully it's going to take longer than that, but a disney trip isn't even remotely worth risking it.
E: Though it's also worth noting even cat 3 is a pretty sizeable fuck you to human existence, and generally something you want to avoid being in the main path of. The main path of irma is looking to be "everything in the state except the western quarter-ish of the panhandle". Seriously, damn thing is looking to be one of the worst storms this state has seen, period. If you don't live here and have things keeping you tied to the state, you seriously don't want to still be inside this state's border right now.
E2: Also, last hour looks to have seen a consensus reached between pretty much every major model we have. Landfall in Miami in about 65 or so hours. Pretty close to certainly going to be something that puts fucking
andrew to shame. Irma is expected to kick the shit out of the impact of most destructive storm to ever slam into this state. Fucking hell.
