Bus versus Boat for Magic Kingdom rope drop/early entry

[Khokhonutt]

I saw a thread from last year with times for the boat for Magic Kingdom early entry and I've read in the past that the bus leaving from the Settlement to Magic Kingdom was more of a sporadic offering during busy times. More recently, though, I've seen comments that seem to indicate the bus from the Settlement to Magic Kingdom may be more regular and potentially preferred for rope drop/early entry.

We'll be arriving next week (3/8-3/14), camping in the Settlement area. I'm curious if anyone with recent knowledge knows, if we're doing rope drop/early entry, are we better off lining up early for the first bus or better off lining up early for the first boat.

Thanks,
Jeff
