Hello Marie,
Welcome to planDisney! Thank you for bringing your question to us, I'm happy to help you with this. What a magical trip you've got on the horizon! I can tell you've done some Disney vacation planning before, and have a practically perfect strategy to utilize
Lightning Lane passes when visiting the parks. Let's talk about your eligibility window, and how that will work with your "split stay" at Walt Disney World.
The booking rule for Lightning Lane passes states that Disney Resort guests are able to purchase them 7 days in advance, starting at 7:00 am Eastern Time, as you mentioned, "for their length of stay (up to 14 days)". I checked with a Cast Member to see if the 14 day availability will still apply to you, even with an off-site gap in the middle of your Disney resort stays. I'm happy to report that because your tickets are continuous, yes, you will be able to purchase and make your selections for all 14 days you'll be enjoying the parks, at one time.
One nuance however is that you will be coming from the UK. International guests must typically wait until they arrive in the United States, before the
My Disney Experience app will allow you to purchase and select your Lightning Lane attractions. However, the Cast Member I spoke to recommended that you call in for assistance 7 days in advance at 7 a.m. EST to 407-939-7765 and they can help.
I hope this works for you to secure all the magical Lightning Lane passes for your vacation, Marie!
