We built ours on a day that we had a mid-day break planned, with our build time around 10:30. It was back in 2019 when HS opened for the day around 5 or 6 AM, so we took a break for lunch off site, then hopped to another park. So we pretty much built the droids, walked around Galaxy's Edge with them for a little bit, then worked our way out of the park. I am very short and found the box pretty awkward to carry, so I'm glad we didn't have to deal with that in the park for very long.
