Should I apply for a non-O retirement visa or do a visa run for my 4-month stay in Thailand?

A user from England is planning to visit Thailand for about 4 months starting at the end of December and is considering whether to apply for a Non-O retirement visa or take a short trip abroad (border bounce) to extend their stay. Comments indicate that a Non-O visa cannot be extended for just one month, but can allow for a one-year extension. For a four-month stay, it may be advisable to obtain a Non-O visa and then do a border bounce. Alternatively, a user suggested using 60-day visa-exempt entries with a short trip to Laos or Cambodia to meet the duration needed.
