On day 28 of my sandbox stay. Can to be with my Thai partner who lives here. Both vaccinated. Looking to travel outside Phuket for a few days to see family. I know I am fine, but as a local she thinks she may need to quarantine in Phang Gna. Off subject a little but if anyone knows for sure
TLDR : Answer Summary
The user is inquiring about traveling outside of Phuket during their 28th day of the sandbox program, alongside their vaccinated Thai partner. Although the sandbox program initially allows for a 15-day stay, the user is under the impression they can leave after this period while still adhering to local COVID-19 travel regulations. One comment clarifies that after completing the sandbox period, travelers can return to Phuket or visit other regions, provided those regions are open for travel. However, they mention potential quarantine requirements for locals depending on their destination.
