Should I visit first Phuket or Hat Yai? My travel options and connections are these two at the moment. Never been in both cities. Are they similar or not about shopping, nightlife, places to see, prices ...

A UK passport question. Does it need to be less than 10yrs from issue date on day of departure, or do they go on 6mths validity after departure date? As my passport was renewed this before it expired, those months were added to the new 10year passport, so it is actually valid for 10yrs 9ths. EU countries are only allowing travel if passport is less than 10yrs old. It expires March 2023 so can this passport be used for Thai travel until Sept 2022, or will it be refused as it’s over 10yrs since issue?
