Yes, they are totally guest friendly, but the rooms suck and you get much more from your money, and closeness to NEP, from the Majestic or Dynasty Inn, plus the room safe.
I just heard a few days ago that they will stop taxing savings accounts in Thai banks. This should stimulate opening and funding savings accounts in Thailand, even if just a bit. Of course, there is no hope of longevity in anything sensible with laws there, so strike while you can if you are ready to open an account. Good luck.
