Should my mother use her Bangkok hotel address or our Chiang Mai home address on the online arrival card?

Hello All,

My mother has a US passport and will fly into BKK after about a week she will come to Chiang Mai.

My question regarding the new online arrival card is about the trip and accommodation section.

Should she use the address for the hotel in Bangkok where she will enter Thailand and begin her trip?

Or should she use our home address in Chiang Mai where she will stay for the majority of her time in Thailand?

Thank you in advance 🙏🏾🙏🏾🙏🏾
