I confirm, this is the hotel I use in BKK. I check in as "A friend of the Tarntawan" I am automatically registered as 2 persons therefore no problem with guests and no extra for the second breakfast !
The nicest little extra are the 6 or 7 business cards that I receive on checkin " Mr, jinks in residence" followed by the Tartawan address !
At a bar I can use the line "Come up and see me sometime" also if you are a little, shall we say tired, one given to the Taxidriver gets you home.
ttfn, jinks.
