Rope Drop Navi River

Hi there. We want to rope drop Navi River on a crowd level 2 for AK. Two questions, how early do you think we need to be at the park? We have a 20 month old with us. Also, how long do you think we will have to wait? I created a touring plan and it says we will arrive to NR at 9:10 and have to wait 23 minutes. Is this accurate?

Thanks
