I can’t speak as Bangkok expert, well 15 years ago maybe when work brought me there a number of times a year for weeks at a time I might have been but n longer.

I just spent, with my wife who'd never been to Asia, 7 nights at the SGS. It’s a superbly run hotel in a great location. Being directly connected to the BTS/ Skytrain at the lobby level which also mean being connected to the Terminal 21 mall and easy access to the Siam Square/ Siam Paragon/Siam center/ MBK is A huge plus. Also from terminal 21 side of Sukhumvit is a MRT/Subway stop with one change you’re at the new MRT stops near the Wat Pho and the Grand Palace. The Westin has similar access it’s just from ground level.

the free happy hour elite drinks in the SGS living room easily equal have a lounge. It’s also fresh squeezed juices and non- alcoholic drinks all day. The happy hour free drinks at the ground level restaurant also. The breakfast buffet in the Lobby level restaurant had a very wide selection plus you have the choice of an ordering breakfast in the Italian restaurant. The SGS doesn’t have the full food option of a lounge in the evening but this being Bangkok finding a good inexpensive meal is far from difficult.

getting upgraded to a suite might be more difficult at the SGS but the standard rooms are quite comfortable and as an elite you should get a butter room one the top few floors.

as far the professional women at SGS. Sure there were some older men with over dressed bored looking Thai women, none that appears to me to as young as working girls that I use to see at the JW back in the day. I was stunned every time we passed the changes in the Nana area the change in the area. I assume Nana Plaza is still tucked back in its soi but the area is remarkably different. The most working girls I saw were ones shopping at the basement level of the Terminal 21 mall.
