do you use your phone on the way to the airport? Or do you use your phone during the 2 hours wait at the airport? Do you walk from your arrival gate to the passport area? Do you have to wait to queue to get your passport chopped? So many last minute opportunities to fill in the form till the very last minute. Don't have to worry. If no one is in the queue just stand at the side to fill in before getting your passport choped to enter thailand. Is that last minute enough foe you?
Thoughts on visa. Depends on how much you're willing to spend.
Thoughts on condo. If you're willing to buy, have the money to buy. Don't mind that it works like a lease, which is obviously cheaper than monthly rental. Personally I don't mind since all the buildings in my country are 99 years shelf life and cost minimum 25 million baht for a studio. It's way cheaper for me here.
The only thing I would advice against. I did the 6 months in out. My condo unit was really dirty and dusty and black when I came back. Although I shut everything and even put in a door gap sealer thing you get on lazada. Even the toilet seat was black even though I closed it. Had to stay in the hotel 3 days till I engaged a condo cleaning service. Bought a new bed as well.
