makes sense (y)
Most people actually do get the eVisas approved, only a few were notified that they needed to submit NEW flight info if they wanted to get the visa as their flights had passed.
My advice would be apply early enough for the eVisa that you have plenty of time to wait out the approval period before your flight.
A tourist visa is valid for 3 months <- meaning you have 3 months after it's issued to ENTER thailand on it and get stamped in for 60 days.
So you can apply really early for those visas.
