My post concluded that if you prefer freelancers like I do (vs. the club scene), the Sheraton wins over the Marriott by a slight margin (as least for choices along Sukhumvit, where I like to stay due to the plethora and proximity of freelancers). I do not have comments to contribute on the Westin, having never stayed there, nor the 4 Seasons, which is not on Sukhumvit.

I am heading back to the LOS in about a week and will be at the Marriott again becasue the Sheraton is no longer an option for me. I'd be interested in my fellow BKK hobbyists opinion about my (again, slight) preference of the Sheraton over the Marriott, or if there are opinions about other hotels along Sukhumvit.

Both hotels are very nice 5 star locations right on Sukhumvit Road, so you really can;t go wrong with either one.

My personal preference is the JW Marriott on Soi 2, i like the location due to the very close location to Nana Plaza, a short stroll from the FL at the Beer Garden on Soi 7, Bangkok Beat on Soi 7-1, and the ample supply of talent that stands along the Sukhumvit Road, next to bus stops, in front of Soi 3 and Soi 5. The MBK Mall is a bit closer, and the Skytrain is overhead amd in front of you, station is one block away. Taxis are plentiful and cheap. Great supermarket and mini indoor mall, with a covered walkway from the JW to the mall, bank, exchange house, starbuck snd McDonalds, and 30 or more indoor stores for inexpensive shopping, and the ease of walking back to your hotel room in 5 minutes with your loot.

That Suk bus stop is a keen location for FL talent, they can stand and pretend to be waiting for the bus, heading up the Soi towards Soi 18-21-30-35 etc. That said, it can be shady and cooler in the afternoon, and it is easy to walk up and approach them for some ST or LT action, the working girls will make eye contact and smile at you. My wingman and I have pulled many nice FL ladies from that bus stop area, a few that were great duets (two ladies who were good friends and ended up being a great pair for ST and LT service) .
The pair came to our hotel room for 800 baht each, and went at it like two cats in heat, all for my viewing pleasure, and then I jumped in at my discretion. You can walk into the Marriott lobby w ladies in tow to your room, basically unchallenged, even though some ladies are obvious " a guest" and others might pass as your TGF.

JW Marriott does not question your choice of guest that you bring back to your room, no ID chedck, no ID collection, so you are on your own if you fall asleep and your lady leaves your room.

JW Marriott is a flagship location, amenities are great for me as a Marriott Platinum members, so the Concierge lounge can offer members free Wifi in the lounge area, free full breakfast, free cocktails and snacks at 5:30-7;30pm nightly, free gym, etc. Wifi has a charge if you use it in your room, and i found it pricey.

JW Marriott rooms are starting to get a bit tired, and they need a refresh of their facitity, but it is sparkling clean, and the staff is well trained and very professional. I have no issue getting a smoke-free room.

Prices at JW Marriott have slowly crept up over the years, and the best room rate is now around $175 USD or more, often almost $200 per night. My JW stays about 3 or 4 years ago were in the $115-125 USD range. If you are on a business exp account, no sweat. If you pay on your dime, it can add up quickly, esp when you add in the tax and VAT and service charges, and such. The JW is often nearly full, due to the many business and government guest who stay there w contract rates.

Same might be said about the Sheraton, which is a great property, and many guys like that location for their own personal reasons.
Sheraton has many nice restaurants nearly, ample FL ladies nearby that are available for ST and LT, and you are a lot closer to Soi Cowboy. I feel Cowboy is a little nicer of a venue over Nana Plaza, plenty of bar girls, some great ladies and plenty of variety for all.

I believe that the great Therme Coffee shop is very close to Sheraton, across the street and one block away, and some real stunners hang out in there after 10 pm each night, plus on the sidewalk outside of Therme. Most girls are ST at Therme, but the talent pool is very nice, though pricey, nightly. Most girls ask 2,000 ST, some ask more it is "up to you".

You need to try both hotels and then compare for yourself, and you can't go wrong. Good luck, you will enjoy the JW Marriott if you choose, and I really like it when I have my civilian GF in town for only a few days, she never complains about the JW, for location, amentities, VIP lounge, and the great service, very comfortable beds, and a 5* experience. A civilian GF or work colleague will not feel uncomfortable at the JW even though a few punters will have obvious younger Thai ladies in tow. It is a very upscale and professional atmosphere.

In short JWM is directly on Suk between Nana and Soi2.
The Majestic Grande is a short ways off Sukhumvit between the same two streets.

The next 4 star is the Landmark which is maybe 100 yards from the corner of Nana and Sukhumvit (btwn Soi Nana and Soi6) going toward Asoke. http://www.landmarkbangkok.com/location.html

Further down near Soi 19 and Asoke interchange (Soi Cowboy) are the Sheraton and the Westin which are directly across the street from each other. If you prefer Sheraton because of points and you can't stay at the Sheraton, you can always choose the Westin (FWIW, when on the company dime, I prefer the Westin).

And on the corner of Sukhumvit and Asoke is the Grand Millennium.

Other options within walking distance to Suk but further off the beaten path are
Soi 11: Fraser Suites or LeFenix (next to QBar)
http://bangkok-sukhumvit.frasershospitality.com/
http://www.lefenix-sukhumvit.com/

Soi 15: Dream http://www.dreambkk.com/

Soi 24: Marriott Service Apartments or The Davis http://www.marriott.com/hotels/travel/bkksp-sukhumvit-park-bangkok-marriott-executive-apartments/
http://www.davisbangkok.net/

or going the other way you can do Wireless Rd which has a LeMeridian (also a Starwood-Sheraton property)

Now there are other upscale boutique hotels in the area, but I assume you're not interested in those.

Why not? You're not the guy who got banned for having 30 girls in his room are you? if so, I salute you!
