Yeah, could be a while for sure. Judging by their snapchats, they got stuck 45 minutes ago, it started moving again 10 minutes later, and then officially had to be evacuated. It was still ongoing as of 5 minutes ago. Just a fair warning.
Also, not sure how the weather is looking over there, but it's raining at my house 20 minutes away from the parks, so you may get some weather delays as well.
