I replied that OP should rope drop, but in fairness, I now realize that is open to interpretation. Currently, a true "rope drop" at HS means around 9:15, when they first start letting folks into the park. If you are there at 10am, you've missed rope drop and it is probably the worst time of day to ride. This is similar to how ROP used to operate in the "before times" when people would show up at 9:01 for a 9am open and wonder how the FOP line got to two hours long already.
In other words, if you are able to enter the park right wen it opens and get in the MMRR line first thing, it is the shortest wait of the day. Otherwise, avoid mornings, but afternoons are bad too so I wouldn't do 3pm either--it is either first thing when park opens or last thing before park closes if you want to avoid a wait.
