that would work but timing the application is important to make use of the validity period. If staying in Thailand 3 SETV might be better and it’s also less expensive.
I have just applied for a METV to go for three months with a couple of trips for 2-3 weeks outside Thailand. I haven’t yet booked the additional trips (one by bus to Laos and the second flying to Vietnam as things are still uncertain if Qatari airspace will have reopened by end of April) so I’m a little concerned they will issue a SETV instead but I’ll need to wait and see.
