Are the lines still long during the week on a non holiday weekend?

9 is a safe bet. You can signup for park alerts which will text you closing and opening due to capacity #travelformortals

I arrived at 12 on a non-holiday and could not get in but they said they would be letting new people in around 3 so I came back at 2: 15 and was able to get in. I agree with the other reviewers you should get there around 9 if you want to get in in the morning... But if you don't get in consider going back in the afternoon and trying again.

Yes ... During this time of year the park will reach capacity and stop admitting new guests at abt 10 or 11 am, sometimes sooner. With this in mind , it is always a good idea to arrive before the park opens at 9 in the morning.

Yes me and my friend actually recently went their it took about 3 hours to get into the park

Emma what park are you talking about? As there are no such devices there last time I went. Adrian, the line is still fairly long even on the week day as it is the summer, I'd try to head there early.
