I think if you're not an early bird, the best strategy for the headliners is to get in line close to park close. We also use the Lines app as the real wait times for rides are usually more accurate than the
MDE or posted wait times and we have found even one hour waits are really only 20 min sometimes. That app is a great resource. However, sometimes we do end up waiting for the popular rides if we really love them. Sometimes there is no way to avoid a wait.
