The Suk 57 suite has a closet when you walk in the room as well as a large clothes closet in the bedroom, a half bath in the living room and, IMO, more stunning views. The Suk 57 suite's bathroom also has an amazing soaking tub up against a large window with an incredible view. The Marquis has a soaking tub, but it's in the interior of the room.

It is also a very short walk to the BTS from the Suk 57 hotel. The Marquis is closer to the middle of Bangkok, at Soi 22, but is much farther from the BTS, especially given the shortcut through the park is currently not accessible.

Both hotels have great service and very good CLs, but the Marquis has the better CL. It may be the best CL in any Marriott property anywhere in the world. Period. Including higher-end Marriott brands. The outdoor CL space is very nice with great views. And while both have excellent service, the Marquis just blew me away with its above and beyond service.

Marquis wins on pool. It's a draw on workout areas. There are several excellent small very inexpensive take-out places and a few street vendors just outside the Soi 57 property, although not as many street vendors as there used to be. The area between the hotel and the BTS station has been cleaned up in the past year, which has some good and some bad results.

Bottom line: These are two excellent, excellent choices. The StR is usually much more expensive and, IMO, not worth it given these two excellent choices. I'm not sure which LM you're referencing. I have not stayed at the one on the river, but recently stayed at the Silom area property and found it to be a big step down from the two Marriotts. There is no CL and the two hour reception in lieu of a CL is chintzy compared to the CLs at the two FS properties. The suite was nice but not as nice. For a first time visitor, I'd probably do the smaller Suk 57, but in doing so you are missing out on the world class service and CL at the Marquis. It's just a little easier to get around if you are closer to the BTS.

As for what's best or tall people, I'm not an expert, but both hotels have very high showers (maybe nine or ten feet up), big soaking tubs, large beds and ample room in the water closet, so it's likely a draw there.
