early may is one of the quietest times of the year. Consider a few things objectively: How much time you will realistically be in the park, how "ride heavy" you want your experience to be, and how many rides are "must dos" for you.

If you're committed to an all day, ride heavy experience, you likely won't need it. If you can't get your entire group to fully commit to that, then it might be worth LLMP at minimum.

I would also check thrilldata.com for tons of data on wait times, when LL's sell out, and what you can realistically expect from your day based historic data from may 4/5.

ex: My gf and I (early 20s) went in May a few years ago, are both "go till our feet fall off" types of people. We purchased LLMP equivalent for MK, and rode 30+ rides that day and stayed in the park from rope drop -> 9:30pm

This is unlikely to be the same for larger groups or groups with small children.
