Hey Howdy Hey Winter and welcome to planDisney!
Park hopping with
Genie+ while taking advantage of
Early Theme Park Entry is the way to go. You can get a few of the more popular attractions knocked out in one park with minimal lines while stacking your Lightning Lanes for your second park so you can stroll on through like a rock star! Thank you for your question on the details of booking Lightning Lanes. You've got a friend in me to give you the timing details.
When you purchase Genie+ for the day in the parks, you will have options when booking. You can book just one park or the "Multiple Parks" option. If you have the Park Hopper Option on your Theme Park Ticket, you can either purchase Genie+ for one of the parks you visit or the "Multiple Parks" option will allow you to book your Lightning Lanes for any of the parks. Your wish is Genie's command!
If you were to purchase Genie+ for Disney's Hollywood Studios in your example, your Lightning Lane selections would be based on times in that park. If you were to buy the multiple parks option, your times would be based on the hours of the park you want to book your Lightning Lane in. So ultimately when you can make your Lightning Lane selection after the 7:00 AM one, would depend on which Genie+ you buy.
As a reminder, Genie+ is available for purchase starting at midnight on the day of your park visit. You can book your first Lightning Lane starting at 7:00 AM and your next one would be either 2 hours after the park opens to the public or after you redeem your first selection. These rules will be in place throughout your day.
I hope this information is helpful so you can better understand your options when planning your day. If you have any other questions, you can
reach out directly to me and I can help get you answers for your Magical vacation!
To Infinity and Beyond,
Nick
