Not sure what you are asking here but I will take a guess?Thanks for posting this. Is it possible to split up the LL’s like you did in the park with MMRR and RnRC when you do the prebooking or can you only do that once you start your replacements in the park?
For speed and accuracy it is best to book the same LLMP Groups for your Group for pre-purchase and then Modify your selections for your sub group members for other experiences. You can make these changes all as you are booking your initial advanced selections.
