Right now, nobody can tell you or predict, what Pattaya will look like, when the "new normal" will be anywhere near "normal". Will Walking street reopen and as what? What kind of tourists will come to Pattaya and what kind of associated "workers" will also come back? Will Jomtien fully become a sleeping village full of secondary homes for Russians, Chinese and rich Thais, or will any Europeans come back to Thailand or did they all find other, closer holiday and retirement places like Spain, Italy, Portugal etc?
My best guess is that we will not know before the second half of 2022, in what direction Thailand - and Pattaya - will be going with regards to tourism and retirement.
