Hiya, Don! Welcome back to planDisney. Thanks for stopping by with such a great question!
You sound like someone after my own Disney-planning heart, Don. I absolutely love a split stay, where my family and I stay at two (or more!) different
Disney Resort Hotels. Experiencing the different locations, theming, dining options and pools feels like two vacations in one! My family and I also have an upcoming three-Resort split stay on the horizon, and I'm more than happy to answer your question about yours.
Since you're staying at a Disney Resort Hotel, you can book your
Lightning Lane Multi Pass and Single Pass selections for your entire stay, up to 14 days, seven days before your arrival. And I think you'll be happy to hear that as long as your different Resort stays are consecutive with no breaks in between and you have valid park admission, you should be able to book your Passes for your entire stay at 7:00 a.m. EST seven days before your first check-in day.
Once you tap into your first Lightning Lane, you'll be able to start making more selections and modifying any of your booked selections, based on availability. My favorite strategy is to make my first Lightning Lane selection as close to park opening as possible and grab another one as early as possible. This increases your odds of snagging a Lightning Lane for a popular must-do attraction from any group! Happy booking!
I hope this helps, Don, and I hope you have the most magical and memorable time at all three of your Resorts! Please feel free to stop by any time with any questions you may have. You've got a friend in me.
See ya real soon,
Mandy
