Another thing to consider. The VQ holds a place in a virtual line, when you arrive your wait usually 30-60 mins. It could be longer or shorter depending on when people called join the queue. For example during fireworks line will be short but after the rush will swell the line.
For ILL we tend to walk on or wait less than 15 mins for those rides. So it’s a time saver if that matters to you. We have done Tron and GOTG many times this year. We love the ILL, we tolerate the VQ because it’s free.
We often do both and book the ILL after we think the VQ will be (can’t always tell) because waiting in VQ line can be annoying AFTER you had just breezed through lol.
