Question for everyone who does park days before the races - do you still do taper runs? I'm worried that a couple of morning 5ks plus full days in the park will be too much, but also worried that just walking around won't be enough.
I guess the question would be - how many runs would you be converting from taper runs to park days? If it's 1-2, you're probably fine. If it's 7-8, then that's probably going to leave you a bit stale come race day.
My wife requires 99% participation from me on our runDisney trips with the family. So I've got to do full parks like everyone else in the family and race too. In my experience, this is what I've done. In theory, I write my plans to emulate the # of days per week in training during the taper as much as possible. Run 6 days per week in training, then taper is 6 days per week as well (although, the volume is dropped and the last intense exercise is about 10 days out from race day). But arguably two of my most successful Dopey attempts have come when I had to adlib the training and cut out a day. So in theory, I would do Mon and Tues as easy days, and then Wed as an OFF day. Then PR attempts at 5k, 10k, HM and Full. But I've found having Tuesday off as well has not precluded me from a successful race day(s) experience.
The other consideration to whether a taper run in FL might be a good idea is a little heat acclimation training. Research shows it takes about 10 days to really start to acclimate, but some HAT helps more than nothing. Since I come from WI (where most of my last training runs are done in wind chills as low as -30F, not much sweating, blood is thicker, etc.), I spend the last couple of weeks of training doing Heat Acclimation training (WAY overdress in training to force significant sweating and trying to cause my body to adapt and thin out my blood, produce more sweat). Haven't really needed the HAT the last two years since it's been cold. But if it were warm, I use this as a substitute for "having" to do any FL runs prior to the races to help acclimation. So it's an additional consideration as to whether a run in FL for taper is a good idea.
Training in the cold, but racing in the heat: The need for heat acclimation
Something I'll add to this that I didn't back then though. Make sure you consider cutting the cool down short so that you don't start to get the chills from removing your personal heat source.
