Hi there, Kari! Welcome to planDisney.
I think you are very wise to plan to head to your hotel for a nap break in the middle of the day. Kids and adults will benefit from some time resting and relaxing and getting out of the heat of the day. Then the whole family will be refreshed and ready for an evening of more fun.
With
Disney Genie+ service, Guests can reserve
Lightning Lane access to over 40 rides and attractions, one at a time,
beginning at 7:00 am. Additional Lightning Lane attractions may be reserved after redeeming the initial selection, or every 2 hours beginning 2 hours after the
scheduled park opening time, whichever comes first. There is no requirement for you to be in the park when making your Lightning Lane reservations, so you can absolutely continue to make selections while taking your nap break. You'll want to select those attractions that have a return time window for when you plan to be back in the park. I like to set an alarm on my phone to remind myself when I am eligible to make my next Lightning Lane reservation. Depending on how long your break is, you could potentially have several Lightning Lane attractions booked for later in the day when you head back to the park, making for a very pleasant evening!
Kari, I hope you and your family have a wonderful visit this week! Please let us know if you have any additional questions. We are always happy to help.
Anne Marie
