Possibly going down for the first time this year. Looking at doing a Wednesday/Thursday in early October. Definitely one night, maybe two. Would express be needed?
I will always recommend Express. Is it needed? You can probably make it work over 2 nights if you wanna pace yourself, so no.
Of course, there's always the option to see how crowds are that night but run the risk of Express being sold out for the night (it being early Oct may be a minimal risk, though). Crowds have been weird. I'll go on a Friday and it'll be slower than a Wednesday, then the next week... it's the complete opposite.
