They will never get rid of LLMP as long as LLPP are it's current prices. That is a revenue loss.
Either than will lower LLPP costs to a point where there is significant conversion from LLMP to LLPP to make up the loss of revenue from removing LLMP or they will just expand LLPP offerings (multiple ride usage, multiple parks etc.)
Essentially they will find whatever combination of LLMP, LLPP, LLSP at whatever price point brings in the most revenue even if that means eliminating one or two of those silos.
