Does anyone have any experience with the airport lounge service offered by BFS Premium Airport Services at Bangkok international airport? The cost is 850 baht per person for up to 4 hours, and as we are in transit for 10 hours in Bangkok I am considering booking the 3 of us in for 2 blocks of 4 hours. I can't find any photos or detailed information about the lounges, though, and am wondering how comfortable they are likely to be. It would be good to be able to actually sleep for some of this time, but if this is unlikely to be possible, maybe 4 hours will do. Any advice appreciated.
