I've only been a reasonable queue xmas 2019 in BKK, then maybe an hour. Other 10 trips, no real issue or delay. HKT no queue in Sept (or March with all the covid requirements).
Recently applied for (in the UK) and obtained a 60 day TR for a new trip Stuart. Came back in about 4 days. Surprising how doing it for a 2nd time seemed a walk in the park. Experience is everything. Seems better than faffing around for an extension after entering visa exempt, and a few pound cheaper I think.
