Can I do a same-day border run from Chiang Saen to Laos?

The user is inquiring about the possibility of completing a same-day border run from Chiang Saen to Laos before their visa expires on April 29th. They have done this previously and seek updated information regarding any changes in the rules. A comment suggests that daily trips from Pai and Chiang Mai are generally fine for same-day returns, but for tourists, a two-night stay in Laos may be required.
