I'm exactly the same, from the uk, and staying 16 days too!! I have the countdown on my desktop, all my calendars, everyday I'm looking at things online to do with Disney world, and every few hours I'll tell my boyfriend how excited I am. Sometimes I do a little dance when I'm on my own haha.
ONLY 38 DAYS 15 HOURS 3 MINUTES AND 45 SECONDS
I've never been before only once to Paris we went for two days, 10 years ago when I was 11. and I think it makes it even more exciting that we'll be taking our 3 year old with us! and she is Minnie Mouse and Princess MAD!!
