Hiya, Lisa, and welcome to planDisney! It's so exciting that you're at Walt Disney World Resort right now! I'll keep this answer brief so you can get back to enjoying the magic!
Lisa, you can select another
Lightning Lane Multi Pass experience as soon as you've tapped in for your first booked selection. For this reason, I prefer to make my first selection for one of the earliest available attractions, even if it's one that typically has a short standby queue. The "My Genie Day and Tip Board" section of the
My Disney Experience Mobile App will show you when you can make additional selections, as well as the availability of Lightning Lane Multi Pass experiences.
While I have you, I'll remind you that you can also save time by placing a
Mobile Food & Beverage Order. I like to do this while waiting in line for an attraction - it feels very efficient!
Lisa, I hope you have the best time during your vacation. Please stop by planDisney with any other questions you have!
Happily,
Jennifer
