I stayed in bangkok 2 weeks in November and 1 week in December, at the Ibis Style Silom (close to CP Tower, 2 min to go to Silom soi 6 massage shops, 5 min to go to Silom soi 4, great great location).
At Ibis Style, no problem to have joiners, they just ignore what you are doing. And this new hotel is packed with gay tourists, many koreans. Can be cruisy between visiting guests contacting each other on Gindr...
At 2100 bahts per night, it is a great place to go IMO.
