yes it seems to be the most stress free option although it is considerably more expensive than the single entry tourist visa and obviously arriving on visa exempt is zero cost apart from the 1900 Bhats if you want an extension (plus a visit to immigration with the required paperwork). My previous two trips were on visa exempt and an extension and then returning back to the UK for several months but next trip in April I want to visit Laos for a few days and probably Vietnam for maybe a week so I can time it in such a way that I won’t need an extension. All above board as well so I’m hoping re-entry will be straightforward.
