What I’m seeing is people confusing ILL$ (individually paid) with G+ (per day paid).
How many attractions you can book per day shouldn’t have ILL$ included in your calculations because you can’t book G+ for those rides anyway. IGNORE ILL$ AT THIS POINT.
Let’s say’s I’m going to MK. The park opens at 8AM and closes at 8PM. The + is for booking G+, the - is for using booked G+. This example is strictly using the 2-hour cool down period between bookings:
+At 7AM I book Haunted Mansion for 1PM
+At 10AM I book Jungle Cruise for 3:30PM
+At 12PM I book Big Thunder Mountain Railroad for 5:15PM
-At 1PM, tap into Haunted Mansion
+At 2PM I book Splash Mountain for 4:30PM
-At 3:30PM, tap into Jungle Cruise
+At 4PM I book Buzz for 7PM
-At 4:30PM, tap into Splash Mountain
-At 5:15PM, tap into Big Thunder Mountain Railroad
+At 6PM I book Barnstormer for 7:30PM
-At 7PM, tap into Buzz
-At 7:30PM, tap into Barnstormer
On slower crowd days you might be able to book earlier return times than 2 hours out. We’ll use MK’s same 8AM-8PM hours and rides but switch up the return times. This example uses a mix of tap and book and the 2-hour cool down:
+At 7AM I book Haunted Mansion for 9:15AM
-At 9:15AM, tap into Haunted Mansion
+At 9:15AM I book Jungle Cruise for 11:30AM
+At 11:15AM I book Big Thunder Mountain Railroad for 12:45PM
-At 11:30AM, tap into Jungle Cruise
-At 12:45PM, tap into Big Thunder Mountain Railroad
+At 12:45PM I book Splash Mountain for 4:15PM
+At 2:45PM I book Buzz for 5PM
-At 4:15PM, tap into Splash Mountain
+At 4:45PM I book Barnstormer for 6PM
-At 5PM, tap into Buzz
-At 6PM, tap into Barnstormer
+At 6PM I book Small World for 7:30PM
-At 7:30PM, tap into Small World
You have to base the next booking on the previous booking. If your last booked attraction is under 2 hours away, you can book as soon as you’ve tapped in (the 2nd tapstile on some attractions). If your last booked attraction is more than 2 hours away then you have to wait 2 hours between bookings.
Keep in mind that you don’t exactly get to choose your attraction window. The next available window will show. If you don’t like that window, choose a different attraction within the window you need or refresh and hope the window you’re looking for at the attraction you want opens soon for booking.
Let’s say I booked Seven Dwarves Mine Train and Space Mountain ILL$ and they’re in there somewhere. I did not list them because they have no bearing on what I book or tap into using G+. Listing them would only cause confusion.
