Hi Melissa and welcome to planDisney!
How exciting that you'll be visiting
Walt Disney World this September. September is actually one of my favourite months to visit as the weather is just starting to cool off a little from the heat of Summer, crowds tend to be manageable and because my all-time favourite Special Event -
Mickey's Not-So-Scary Halloween Party, will be taking place.
Melissa, you got it in one! Your
14-Day UK and Ireland Exclusive Disney Magic Tickets, include 14-days of theme park admission to be used across an 18-day window. So, if you are due to arrive on 9th September, your park tickets are valid any 14 days from 9th - 26th September.
Disney Magic Tickets include Park Hopper access which allows you to enjoy multiple theme parks on the same day. You are therefore quite right in saying that you could visit all 4 theme parks on the same day and this would only use 1 of your 14-days worth of theme park admission.
In addition to this, your 14-day Magic Tickets also provide you with a separate 14-days worth of
Water Park admission to Disney's Typhoon Lagoon Water Park or Disney's Blizzard Beach Water Park (subject to seasonal opening).
I hope that this has answered your question, Melissa. Please feel free to re-visit us, here at planDisney, if we can be of any further help with the planning of your trip - you can even
ask me a question directly.
Wishing you a magical holiday filled with memories which will last a lifetime!
Emma
