When we do travel, we generally stay in hotels that don't submit a TM30. The missus checks in with her ID so they don't see my passport. When we do stay at a place that asks for my passport, I submit a TM30 online via the section 38 app when we return home. I know the rules changed re: TM30's and submitting a TM30 is probably not required in this case, but I try to avoid potential situations which could arise later due to NOT submitting a TM30. We are all aware of the general lack of consistency in Thailand, where different offices, and indeed different officers, can interpret things differently.
