Do I need to register with local police when arriving in Thailand, or does my hotel take care of it?

When arriving in Thailand, it is important to register your presence. While hotels generally handle this process by filing a TM30 with the immigration office, it is your responsibility to ensure it is done within 24 hours. Some landlords may not file the TM30, so it's advisable to confirm this with your hotel or landlord. If you do not plan on extending your stay or interacting with immigration, you may not need to worry about this registration. However, if you intend to apply for an extension, having the TM30 filed and a printout of its confirmation will be necessary.
