definitely not!!!Are you retiring to Thailand ? If not, why would you need a retirement visa? Have you looked it up on the Thai Embassy website ? Its a big decision.
You can do the 60 day visa exempt twice, without much scrutiny as you will be leaving before the 90 days. ( 60 days visa exemption and 30 days extension at an immigration office in Thailand). Stick to the rules you'll be ok with doing this twice. They have not yet decided to reduce the 60 days to 30 . Why go to Bali for one week ??? It's a long flight , and Costly for a week. Id leave that out and stick to neighbouring county. Vietnam deserves 2 weeks, Siem Reap Cambodia is a sight to see if you get up very early. Laos ...Luang Prabang is very pretty, also Malacca and Langkawi in Malaysia.
Important, when are you planning to travel , careful of the rainy seasons.
they often do not like turn around, in and out in a day or 2. Staying a few days in Penang or Siem Reap or Saigon always goes down better. And fly, air Asia is cheap.
it's better to fly generally on a border hop, or take an agency group trip border hop. Plenty about. Take the best, it's cheap..The agencies are usually better received than a person alone. Some immigration officers can be awkward. Speak nicely and dress well. They can ask to see 20 000Baht cash to prove you're not broke.
