I would not suggest Connrad Bangkok do much. I booked in here 2 rooms for a week and needed a business room for a couple of hours. Having already signed up for Internet access for the week, we found there was no wifi in the busines centre, yeah weird I know. It was no problem though they would put Internet access on for us, at 1,000 baht / hour/ per machine (which were BOTH signed up for the week). I declined their offer, pating 1,000 baht per hour for the room is one thing but and EXTRA 2,000 Baht / hour for two laptops yo connect to the already paid for internet was something else !
I also needed a copy of my passport, also don in the business centre, no problem, 100 baht / page !
