From what I’ve seen stacking isn’t as easy with your first reserved park, especially MK. When I’ve checked the tip board arrival windows are usually within the hour for MK for a big portion of their rides. You can only book next available if it’s your reserved park.
If you are hopping, stacking seems to work better. At or around 7 am make a 3 pm for SDD. Around 11 am make a 5 pm for Smugglers. At 1 pm make a 4 pm for TSM/RNRC/TOT. If you bought ROTR and MMRR at 7 am you could walk into the park at 3 pm with 5 LL and make a new one as you arrive and keep rolling them out. Of course if times work.
That’s how I’m understanding it anyway.
