This is confusing because you can still have more than one booking at a time, you just have to follow the "use my selection or wait 120mins- whichever comes first" rule.
let's say MK opens at 8am.
if I book at 7 for a return time of 3-4pm
I can book again at 10am. - I get a 5-6pm time
I can book again at 12- I get a 6-7 time
I can book again at 2- I get a 7-8 return time
its 2pm and I am now holding 4 bookings. I just entered the park for the day..
alternatively
I book at 7am and I get a 8-9 return
I enter my ride at 830- I can book another. I get 9-10 return time.
I enter my ride at 9- I can book another- I get a 1-2 return time.
I've used 2
genie+ without stacking and now I can book another one at 11.
at 11 I book with a 3-4 return time.
im now holding one for 1-2 and one for 3-4
at 1pm I would be eligible to book another. I do and I get a 5-6 return time.
I use my 1-2 return time one.
I use my 3-4 time one and I'm eligible for another because it's been 2 hours since I booked my 5-6 one.
you can still stack.. you just Have to follow the "use the LAST one I booked or 120 mins- whichever comes first"
