I stayed at the Marriott on the river. The room was really nice. As a plat member, I was given the royal treatment and the hotel was really nice. There is a shopping center adjacent. NO CL but I get a full breakfast in the resturant every day, something in the evening in the lounge (don't remember but I think I had a dollar credit amt), 2 hrs free in business center, spa discount, Etc. I was going to use points but it was so cheap that I just paid for it.
I really enjoyed Thailand but when I was there, there were threats and bombs. Some people were killed. The hotel sent a car to the airport for me but when we arrived at the hotel, security checked the whole car and used mirrors to see the under side. I really enjoyed the sites and people but it would have been better if the political climate was better. Plan accordingly!
Its been awhile since I was there. And was lucky enough to have contacts to get us around passport control. Stayed at the Oriental, which at the time was the top rated hotel in the world. They picked us up in a Rolls Royce, we never saw our luggage after they collected it in the ap until in our room, unpacked, pressed, hanging in the closet. It was a travel experience I will never forget. Long before Marriott was there.
Sorry to say that my trips to Thailand were before Marriott had a property there, so I have only stayed at the Mandarin Oriental, Hyatt and Dusit Thani chain that is owned by one of friend's families. They stayed in Khao Lak for their honeymoon at a resort which was a gift from the family, as there was no Dusit Thani there in those days either, and they have nothing but wonderful stories about their stay there.
I was never disappointed by any hotel in Thailand as the Thai culture is so gracious and has such a high standard of hospitality..
All hotels that I stayed in included breakfast, so I don't know if that is just a standard service in Thailand or not. I really enjoyed the choice between western breakfast, and Thai breakfast. If you get a chance to try the Thai breakfast I think you will find it enjoyable. Its a porridge made of rice that they add pork, chicken or shrimp too, with seasonings like fresh corriandor.
Just remember the Thai (and most Asian country) customs of always remembering to smile at people, never display negative emotion or be confrontational, and always start conversations off with social pleasantries and you will always get very positive responses. If possible try to get to know them and their families, and I always carried pictures of our family, home, holidays, and of course pictures of snow and ice. People loved this, and even asked if they could keept one. It always surprised me that they would pick a picture of the family at Christmas dinner, and not the beautiful pictures of the roses on the deck overlooking the lake.
Oh, and I always carry some gifts of typical american things like maple syrup in the little bottles, small packets of wild rice, pecans. Also be prepared to make receipe suggestions like cook the wild rice like any other rice, try the maple syrup over vanilla ice cream, etc. You will make many friends and have a wonderful trip.
