Possibly true with some embassies but for my first 60 day tourist visa obtained via Spanish Embassy in Madrid. I had to give them a genuine "full" itinerary. Accommodation had to be shown as booked and confirmed, towns and my travel intentions, e.g. sailing, trekking, attractions were all requested of me.
I just made up a route from BKK across to Kanchanaburi then south down to Krabi, booked hotels with free cancellation policies staying 3 or 4 nights ending with 10 nights in Krabi and flying out of there to Kuala Lumpur on my 59th day.
Of course once in possession of the tourist visa I cancelled all accommodation bookings and only kept the flight remaining for proof on entering Thailand. Thankfully, the throwaway fight only cost 26€. It was an intense requirement.
