Do I need to report my accommodation when alternating between locations on a Non-O visa in Thailand?

The user is inquiring about the need to report their accommodation status while on a 90-day Non-O entry visa in Thailand, particularly when alternating between two locations: Uttaradit and Chiang Mai. Comments suggest that if both locations are under the user's control without a landlord, they only need to use one address consistently for their 90-day reporting, especially when applying for an extension. There are recommendations to keep the address the same for reporting purposes and that the user should file the TM30 for the location where they intend to apply for an extension.
