What should I know about doing a visa run at Chiang Khong border for an education visa in Thailand?

(Feel free not to post this if it’s not helpful/important information) Yesterday, we successfully did a visa run at the Chiang Khong border crossing into Laos and back. Our education visa was about to expire, so we entered back into Thailand on a visa exempt stamp (which will give us 30 days to apply for our new visa). Immigration was very empty on both sides. It took our family three and half hours to make the whole loop. One hour was just waiting for the shuttle to take us across the bridge. It’s only running about every 30 minutes. The health checks on both sides also added time. I’m not sure what other information would be helpful to share, but I’d be glad to answer questions about our experience.
