Your first couple of days are looking kind of wet, so have all of your 'keeping dry' stuff. After that, on the forecast I looked at anyway, it looks much more normal.
I hope you're feeling all better by take-off time. Remember what you said to Chelsea (I'm pretty sure it was you) about the countdown stickers, and take that advice -
tell your nerves to chill!
It's gonna be lots of fun, but not perfect: a little rain, a little heat, some people who are making your lines long, a broken down ride, a few that will want to stand too close, some wheels that will want to clip your heels
(from oldsters and youngsters), somewhat over-priced food, loud toilets, a few noisy neighbors...
but, it'll be grand!
The wonderful sights, sounds, and smells of the magic
that is Disney will prevail, and you'll have a great time! Then you'll come back and share it with us as you relive it in pictures and stories.
Not a bad life, I'd say.
If I don't get back over here to say goodbye, have an awesome, awesome time for all of us!
