Had a super short stay (<24 hours) in Bangkok a couple of weeks ago. We figured it was a good chance to try somewhere new, but at the last minute, we decided to stick with SGS and were glad we did. We had a very early flight so we had to leave the hotel before breakfast, but they graciously sent us with three boxed breakfasts that included coffee, oj, fruit, muffins, and sandwiches. It was kind of over the top and we almost felt uncomfortable pulling out our huge spread when we got to the airport.
Used an SNA and got a suite. Not sure if it was necessary as happy hour didn't seem as crowded as previous stays, but after 5 nights in a regular old room at Sheraton Singapore, it was a nice way to end the trip.
Funny note: I had forgotten how far our money went at Terminal 21 when we were there last year and I loaded 300 THB on a card when we went over for lunch. There were 3 of us and we were pretty hungry, but it was comical trying to order enough food to spend it all. In the end, we came pretty close.
