Thanks for the response to my first question. I have just one more:

Does anyone know the hours for this lounge? I have two layovers and a departure in Suvarnabhumi (none of them on a SkyTeam airline), and I believe I am entitled to access as a WorldClubs member. None of the flights are on a SkyTeam airline, though--Thai Air Asia and Cathay Pacific--so I am worried it might not be open. Here are the times I will need it:

-Midnight to 7am wednesday-thursday overnight
-9:30am to noon monday
-7am to 9am sunday

I have searched and searched to find a number to call--the Northwest people were no help. Any ideas?
